Ringing in your ears


Tinnitus, that phantom ringing in the ears that affects thousands in Canada, is generated not by the ear, but by neurons firing in the brain, according to a North American research team that includes a McMaster University scientist.

“The tinnitus is not generated by processes in the ear, but changes in the brain when hearing loss occurs,” said McMaster professor emeritus Larry Roberts, with the department of psychology, neuroscience, and behaviour. 

Neurons, he said, are meant to talk to each other. When the ear stops talking to them, usually because of hearing loss, they start talking to themselves and this in turn, generates the ringing. “The sound is generated by neuron activity.”

Roberts said the conclusion is the result of collaborative work in the past decade, but said many people are not aware it’s the neurons, or changes in the brain producing tinnitus. Now the question is: how is the noise generated in the brain? “What are the neurons doing, and where are they doing it?” he said. “Our work will assist.” 

Understanding how it happens might lead to finding a treatment. The findings also help scientists understand why tinnitus is such a difficult problem to treat, he added.
They also point to the importance of prevention.

About 300,000 to 350,000 people in Canada, or about one to two per cent of the population, suffer from severe tinnitus. About 10 to 12 per cent of all Canadians have some form of tinnitus, he said.
Peter Austen, acting president of the Tinnitus Association of Canada, has suffered from a severe form for five years and says he’s researched everything and tried everything. He says it’s long been known that tinnitus is a phantom noise generated in the auditory cortex in the brain.

The main problem with tinnitus, he believes, is that people are trying to find cures but none of what is out there will help. 

“There’s no cure. Only management,” he said.

“You never want to get it. Don’t ever go to a concert without wearing earplugs,” he warns. “Teenagers don’t realize what they’re doing to themselves.”

Roberts said although tinnitus is most common after age 60, chronic tinnitus can happen at any age and it is a major cause of disability in soldiers returning from Afghanistan and Iraq.
Studies show hearing loss among young people is increasing and this may also lead to an increase in tinnitus, he said.

“If there’s a price to be paid for listening to loud music, it’ll be later in life,” Roberts said Thursday before leaving for the annual Society for Neuroscience meetings in San Diego where he and the other researchers will present a symposium on their findings.

Roberts said U.S. data shows 12 to 13 per cent of adolescents have hearing impairments. With iPods so common and the use of ear buds almost universal, this is quite alarming because more children will be more susceptible to tinnitus as they grow older, he said.

Scientists Show How Tiny Cells Deliver Big Sound In Cochlea


(Original Link - http://www.sciencedaily.com/releases/2009/10/091022114319.htm)

Deep in the ear, 95 percent of the cells that shuttle sound to the brain are big, boisterous neurons that, to date, have explained most of what scientists know about how hearing works. Whether a rare, whisper-small second set of cells also carry signals from the inner ear to the brain and have a real role in processing sound has been a matter of debate.

Now, reporting on rat experiments in the October 22 issue of Nature, a Johns Hopkins team says it has for what is believed to be the first time managed to measure and record the elusive electrical activity of the type II neurons in the snail-shell-like structure called the cochlea. And it turns out the cells do indeed carry signals from the ear to the brain, and the sounds they likely respond to would need to be loud, such as sirens or alarms that might be even be described as painful or traumatic.

The researchers say they've also discovered that these sensory cells get the job done by responding to glutamate released from sensory hair cells of the inner ear. Glutamate is a workhorse neurotransmitter throughout the nervous system and it excites the cochlear neurons to carry acoustic information to the brain.

"No one thought recording them was even possible," says Paul A. Fuchs, Ph.D., the John E. Bordley Professor of Otolaryngology-Head and Neck Surgery and co-director of the Center for Sensory Biology in the Johns Hopkins University School of Medicine, and a co-author of the report. "We knew the type II neurons were there and now at last we know something about what they do and how they do it."

Working with week-old rats, neuroscience graduate student Catherine Weisz removed live, soft tissue from the fragile cochlea and, guided by a powerful microscope, touched electrodes to the tiny type II nerve endings beneath the sensory hair cells. Different types of stimuli were used to activate sensory hair cells, allowing Weisz to record and analyze the resulting signals in type II fibers.
Results showed that, unlike type I neurons which are electrically activated by the quietest sounds we hear, and which saturate as sounds get louder, each type II neuron would need to be hit hard by a very loud sound to produce excitation, Fuchs says.

The cell bodies of both type I and type II neurons sprout long filaments, or axons that head to the brain, and some others that connect to sensory hair cells. Unlike the big type I neurons, each of which make one little sprout that touches one sensory hair cell in one spot, the type II cells have projections that contact dozens of hair cells over a relatively great distance.

"Somewhat counter-intuitively, the type II cell that contacts many hair cells receives surprisingly little synaptic input," Fuchs says. "In fact, all of its many contacts put together yield less input than that provided by the one single hair cell touching a type I neuron."

Fuchs and his team postulate that the two systems may serve different functional roles. "There's a distinct difference between analyzing sound to extract meaning -- Is that a cat meowing, a baby crying or a man singing? -- versus the startle reflex triggered by a thunderclap or other sudden loud sound." Type II afferents may play a role in such reflexive withdrawals from potential trauma."
This study was supported by the National Institute on Deafness and Other Communication Disorders, and a grant from the Blaustein Pain Foundation of Johns Hopkins.

Authors on the paper are Fuchs, Weisz and Elisabeth Glowatzki, all of the Center for Hearing and Balance and the Center for Sensory Biology, Johns Hopkins University School of Medicine.

Built-in Amps: How Subtle Head Motions, Quiet Sounds Are Reported to the Brain


(Original Link - http://www.sciencedaily.com/releases/2010/02/100209091842.htm)

The phrase "perk up your ears" made more sense last year after scientists discovered how the quietest sounds are amplified in the cochlea before being transmitted to the brain.

When a sound is barely audible, extremely sensitive inner-ear "hair cells" -- which are neurons equipped with tiny, sensory hairs on their surface -- pump up the sound by their very motion and mechanically amplify it. Richard Rabbitt of the University of Utah, a faculty member in the MBL's Biology of the Inner Ear course, reported last spring on the magnification powers of the hair cell's hairs.

Now, Rabbitt and MBL senior scientist Stephen Highstein have evidence that hair cells perform similarly in another context -- in the vestibular system, which sends information about balance and spatial orientation to the brain.

"The bottom line is we have 'accelerometers' in the head that report on the direction of gravity and the motion of the head to the brain," says Highstein. "What we found is they respond with a greater magnitude than expected for very small motions of the head. This brought to mind a similar amplification of very small signals by the human inner-ear cochlea. And, in fact, the vestibular system and the cochlea have a sensory element in common: the hair cells." Rabbitt and Highstein found that, in both the auditory and the vestibular systems, the hair cell response exhibits "compressional nonlinearity": The lower the strength of the stimulus, the more the hair cells "tune themselves up to amplify the stimulus," Highstein says.

The toadfish was used for this study. "What's interesting is the boney fishes evolved some 3 to 4 million years ago; subsequently this feature of its hair cells was apparently co-opted by the mammalian cochlea. Evolution conserved this feature, and the mammal later used it to improve hearing sensitivity," Highstein says.

Sony ends sales of cassette-tape Walkman players in Japan


(Original Link - http://www.japantoday.com/category/business/view/sony-ends-sales-of-cassette-tape-walkman-players-in-japan)


TOKYO — 

Sony Corp has ended domestic sales of its Walkman music players for cassette tapes due to flagging demand amid the spread of portable digital devices that play music downloaded online or from CDs via computer, company officials said Friday. Sony had already finished shipments of cassette Walkmans this spring, meaning the iconic product will disappear from the Japanese market after stock runs out.

Sony’s cassette Walkman player became a global hit on its launch in 1979, selling about 220 million units by the end of March this year. But its sales slumped in recent years in parallel with the company’s intense competition with Apple Inc of the United States over digital music players.
To counter Apple’s popular iPod series, Sony launched digital Walkman players that became the mainstay product in its Walkman lineup.

The company officials said Sony will continue the production of cassette Walkmans, undertaken by a Chinese manufacturer on consignment, for overseas markets.

There are no plans at present to halt the production of Walkmans for CDs or MDs although their demand is also on a downturn, according to the officials.

Where is the Underground?






In an age when music is available anywhere, anytime, where do you find the underground, and what defines it? 


At festivals around the world guitars are being played with handheld fans, contact microphones are exposing the hidden sounds of the most basic acts of friction, and turntables are being played without any records on them. I have even seen amplified glass being eaten as if it were as delicious as chocolate.

For the critic Simon Reynolds, ‘the web has extinguished the idea of a true underground; it’s too easy for anybody to find out anything now.’ But the underground is not simply about access, nor is it a mere description of the physical context of the music. The underground is essentially a practice, a cultural philosophy of music that exists outside of the mainstream. This philosophy, rather than being extinguished, has actually been invigorated through new innovations in social media, digital technology and audio culture.

What do I mean when I say ‘underground’? Historically, the underground could include 1960s psychedelic music of the US hippie counterculture, the DIY anti-corporatism of 1970s-era punk rock, the early 1990s-era of grunge rock, or 1970s and 2000s-era hip hop. Running through these styles is an emphasis on authenticity and a comparative lack of commercial appeal, but the underground I’m talking about is distinct from these. Though underground music sometimes crosses paths with popular music, its ambitions lie elsewhere. My own view is that contemporary improvisers, noise musicians and drone artists, broadly, make up the underground of today, and though the field is large and the styles broad, these musicians’ general aesthetic ambitions, combined with their comparative lack of public exposure, means that it still makes sense to consider them together as a discernible international scene.

Key to the underground philosophy is that it represents an aesthetic third space, one which eludes conventional boundaries. The ancestry of both this idea and today’s underground musical style can be traced to the eclectic activities of such sixties musicians as the Nihilist Spasm Band, Henry Flynt and Captain Beefheart (and further back again, to Dadaism). The American music journalist Ellen Willis called the Velvet Underground ‘anti-elite elitists’, expressing something of the underground’s peculiar mix of high and low cultural practices.

The underground is a guerrilla philosophy that is mostly defined in relation to the mainstream, and so could be anything at any time. Defining it in concrete, practical terms is therefore a tricky business. Frank Zappa tried: ‘The mainstream comes to you, but you have to go to the underground’. In the sixties, seventies and eighties, the fact of having to go to the underground was more clear cut, but since the advent of digital technology and the web, such a relation has become confused. MP3 blogs and file sharing websites, in addition to social networking platforms such as MySpace, have all facilitated the spread of underground music in a way that was inconceivable in the pre-internet age, when small fanzines and bootlegged tapes dominated. Everything has become available, everywhere, all of the time: culture has become flat.

Audiences no longer have to go to the underground in the same way that was required of them in the seventies, for example. As Martin Raymond, co-founder of trend forecasting company The Future Laboratory, says: ‘Trends aren’t transmitted hierarchically, as they used to be. They’re now transmitted laterally and collaboratively via the internet. You once had a series of gatekeepers in the adoption of a trend … but now it goes straight from the innovator to the mainstream.’

But the idea of the underground lives on, despite the possibility of general access. The word ‘underground’ connotes a sense of concealment, even of contraband, and this is at the heart of what still defines it as a musical philosophy. The music’s general abrasiveness repels the mainstream; the distinct willingness of the general public to either turn away or ignore its existence in the first place is what gives underground its identity, not some farcical public inability to locate it.

Cities with a rich cultural history and with firmly established public arts institutions lead the field in terms of underground scenes. Berlin, for so long cleft in two in every way imaginable, has hosted a thriving underground for decades, and particularly since reunification in 1990. Orientating around totemic minimal techno producers such as the duo behind Basic Channel, Mark Ernestus and Moritz von Oswald, and Robert Henke from Monolake, and also noise and experimental pop musicians such as Felix Kubin and Gudrun Gut, the Berlin underground scene connects back within the country’s own history to the fertile days of the Weimar Republic. But it also connects outward to other underground scenes through digital means, through festivals such as Transmediale and MaerzMusik, through venues such as Berghain, and through record shops such as Hard Wax in Kreuzberg, to name only a few of the conduits to other scenes.

London can boast a similar vitality, despite Mayor Boris Johnson’s reliably baffling recent comments lamenting the lack of a ‘counterculture’ in the city. In contrast to the largely dance-orientated music of Berlin, it is networks of improvisers and noise musicians that dominate the London underground. Building on a politically engaged tradition of underground music-making that originally developed in the sixties, musicians such as John Butcher, Sebastian Lexer, Kaffe Matthews and Eddie Prevost, among many others, deepen the cultural discourse through regular live activity at venues such as the Vortex, Boat-ting and CafĂ© OTO. Shops such as Sound 323 formerly provided the physical core for London underground musicians, but that function has largely been usurped by the aforementioned venues, in addition to the important web presence that London labels and promoters such as the leading black metal, black ambient and noise organisation Cold Spring, and disparate webzines and blogs, maintain.

In both London and Berlin, and in other important cities for underground music around the world (Tokyo comes immediately to mind), comparative economic wellbeing has made it easier to nurture underground scenes. The example of the USA, a country with perhaps the leading DIY tape and noise scene in the world, is a case in point. That DIY scene derives a kind of implicit practical support from the USA’s economic security that would be impossible in countries with less stable economies.
The institutional aspect of underground culture – its relation to the mainstream – has remained relatively unchanged over the past few decades. The impact of the web, however, has led to a fundamental shift in recent years in the nature of the underground’s very existence. The underground has largely shifted from physical meeting places such as record shops to virtual networks organised through and on the web. Underground musicians themselves are keenly aware of this, promoting their activity through their own websites, or through independent, web-focused labels, and transmitting much of their music through social media such as Soundcloud.

The web has been pivotal for the underground scene in Ireland, a country in which the institutional frameworks that buttress activity in London and Berlin simply do not exist. The country nonetheless boasts a small but fervent underground scene. An array of leading figures constitute the artistic and promotional firmament of Irish underground music. Gavin Prior, improvising noise musician, head of the Deserted Village label, and member of such bands as Wyntr Ravn and United Bible Studies, and Andrew Fogarty of weird-synth outfit Boys of Summer, of Toymonger, and head of Munitions Family label, both in Dublin; and Vicky Langan, who runs the Black Sun weirdo/outer limits music and film nights, and Paul Hegarty, of the extreme noise-group Safe and head of Dot Dot Music, both in Cork, are just some of those involved with developing a cultural alternative to the mainstream. A particularly healthy scene has developed in the past ten years or so in Cork, but Dublin, with almost ten times the population, still has the edge: artists like the Jimmy Cake and the Redneck Manifesto leading an avant-rock centred field, and Children Under Hoof, Patrick Kelleher and His Cold Dead Hands (who is notably on the Skinny Wolves label, another player in all of this) and others gigging in venues such as Anseo, Whelan’s, The Shed and the contemporary art space The Joinery, and organising the (echt-underground) ‘box socials’ on South Circular Road.

It is difficult for underground scenes to reach a degree of maturity without economic and institutional stability, but the relative health of the Irish underground scene testifies to the ability of underground cultures to flower in adverse economic or cultural circumstances, often thanks largely to the collective enthusiasm of a relatively small group of people. Similar processes can be identified in other burgeoning scenes around the world, such as that in Buenos Aires, where local musical traditions combine fruitfully with experimental dance styles and contexts, or in Beijing, where recent economic accomplishment, amongst other cultural factors, has allowed a diversity of underground musical activity to flourish. This is the case particularly with regards to the scene that has developed around the improviser and promoter Yan Jun and artists such as FM3, the former of who runs an annual underground music festival called Mini Midi, and also a famous series of improvised music weeklies, ‘Waterland Kwanyin’.

The guerrilla nature of the underground, then, persists in the digital context, and has even been invigorated by its new possibilities for international communication. The institutional and cultural richness of larger metropolitan centres such as Berlin and London has led to the development of a strong backbone of underground musicians, many of whom have been able to, by virtue of the platform given to them in their own country and through the web, connect across local boundaries with musicians and promoters from across the world. Gavin Prior’s wonderful coinage, ‘To hell or to internet’, sums up the situation for underground musicians from smaller musical centres. Economic stability can facilitate the spread of underground musical cultures, but it is not required, with the many and varied promotional and communicative possibilities of the internet proving a decisive recent factor in the nurturing of small, interpenetrating international underground scenes. The very existence of an underground culture – antagonising the mainstream, redreaming its resources for obscure ends, opening up a crucial space for experimentation and for critiquing the mainstream – in fact exemplifies the type of positive, web-mediated collective space that our new digital age has promised for so long.
