Bio
I have been pursuing research into the question of how the brain makes sense of sound for almost 30 years.
Hearing is the telepathic sense we all take for granted, allowing us to sense the presence of others in our environment with our eyes closed, or, via the medium of spoken language, to teleport our thoughts into another person’s mind via invisible vibrations. We learn at school that the key to these near miraculous abilities are “sound waves”, minuscule ripples of air pressure that radiate out from physically excited surfaces. But there is nothing “wave like” about our subjective perception of sound. Loudness maps in a very non-linear way onto wave amplitude, and while many people are taught that wave frequency maps onto the percept of pitch (that is whether a note is "high" or "low"), experts know that this is such a gross oversimplification as to be almost completely wrong. The timbre of a sound, perhaps its most distinguishing or characteristic feature, has so many perceptual “dimensions” to it that experts still do not agree on how many dimensional timbre is and what the most important dimensions are. Most of us are also able to perceive sound as highly spatial, being able not only to tell the direction where a sound comes from, but also, to an extent, the distance, and whether the sound travels through a small or large room to our ears. We are also pretty good at guessing the physical dimensions of sound sources, as well as what they are made of. And we are so adept at discovering regular rhythms in sounds that we effortlessly extrapolate them into the future or fill in gaps when part of a sound sequence is obscured by masking noises. All of this illustrates the astonishing sophistication of the central auditory nervous system, which uses still only partly understood neural computations to transform neural impulses triggered by physical sound waves into psychoacoustic, perceived qualities of sound such as loudness, pitch, timbre, rhythm, size or spatial direction, and uses those to create key aspects of the sensory world we inhabit. Improving our still rudimentary understanding of the neural mechanisms underpinning these remarkable transformations is not just a fascinating intellectual challenge, it is a necessity if we want to improve our ability to respond to the needs of hearing impaired cochlear implant users, whose ability to perceive the pitch or the spatial direction of sounds is dramatically diminished, or of those of unfortunate tinnitus sufferers who are disturbed by irritating phantom sounds that have no physical origin and appear to be created entirely in their heads.
