Welcome to auditoryneuroscience.com


This site contains sound examples, color figures, animations, links and other materials to support the study of auditory phenomena.

Postdoctoral position and PhD studentships available in Auditory Neuroscience

Jan Schnupp is setting up a new laboratory at the City University of Hong Kong Biomedical Sciences Department from spring 2016 and is recruiting talented early career scientists and students interested in doctoral studies in auditory neuroscience.

We will be carrying out electrophysiological and psychoacoustic work on humans and rodents to probe neural mechanisms of auditory perception. Competitive salaries or scholarship funding is available for successful applicants.

Hear it Like Your Grandmother - Simulating Age Related Hearing Loss

As we age, our auditory sensitivity often declines, and the average decline is perhaps a lot more than you might think!

How We Hear Speech

Our very brief introduction for lay people to the science of speaking and hearing speech.

talking kids

Our ears are our gateway to the world - and to each other.


This javascript app calculates a spectrogram from the input to your computer's microphone. (You may have to adjust the sensitivity a bit.) A spectrogram is in some ways similar to the activity pattern that auditory nerve fibers send to your brain, so you can use this spectrogram app to visualize what various sounds or speech would "look like" to your brain. You can pause the spectrogram by clicking on it.

Two Formant Artificial Vowels

A little interactive demo to illustrate the role formants play in vowel sounds.

The McGurk Effect

The "McGurk Effect" illustrates that what our eyes see can influence what we hear. The video here below shows Prof Patricia Kuhl's demonstration of this effect. She is mouthing the syllables /ga-ga/, but the video has been dubbed with a sound track of her saying /ba-ba/. Your eyes can tell that the lips are not closed at the beginning of the syllables, and they therefore tell your brain that the syllable cannot be /ba/, even though in reality it is.

Human Articulators in Action

This movie is from the website of the Speech Production and kNowledge Group (SPAN) at the University of Southern California. It shows the vocal tract of a young lady, imaged with magnetic resonance technology, while she talks about her love of music.

Dancing Outer Hair Cell - Video

Since the amplitude, and hence the mechanical energy, of airborne sounds is tiny, the cochlea mechanically amplifies the incoming vibrations. The motors which supply this mechanical amplification are the outer hair cells. Like inner hair cells, they use stretch receptors associated with the stereocilia at their tips to sense vibrations and convert them to electrical currents. But only in outer hair cells are these currents used to control length changes which parallel, and reinforce, the incoming mechanical vibration.
