The Sheffield culture guide written by in-the-know locals

Sound is detected by extremely sensitive sensory receptors called hair cells that are located in the cochlea. The name 'hair cell' derives from the hair-like elements (stereocilia) that project from the cell’s apical surface. During sound stimulation, the stereocilia vibrate, initiating the conversion of sound into an electrical response. This initial electrical response is then relayed to the brain enabling us to hear different sounds.

The major challenges for Sheffield’s Hearing Research Group are to understand the molecular and cellular mechanisms involved in the development, function and ageing of our auditory system. This is critical for our understanding of numerous different forms of hearing loss and deafness and for the development of gene-based therapies.

Researching hearing with zebrafish

Watch the Hearing Research Group’s video on using zebrafish as an animal model to study deafness.

For more information about zebrafish biology how they are used in research check out the Whitfield Lab’s Zebrafish Senses presentation on Prezi.

How easily is our brain tricked?
Activity recommended for ages 10+

Watch these videos explaining some audio-visual illusions.

Shepard Tone:
A Shepard tone is a sound made out of multiple sine waves which create an auditory illusion.

Sine waves separated by an octave are layered on top of each other and progressively move up the scale. The higher pitch tones become quieter. The middle pitch tones stay loud. The bass pitch tones become progressively audible. As a result, you can at all times hear at least two tones rising in pitch, so that your brain is tricked into perceiving a constantly ascending tone!

Ascending Shepard tones were used by Hans Zimmer in the soundtrack of Christopher Nolan's Dunkirk to create a feeling of building tension.

The McGurk Effect:
The McGurk effect is an example of the input of one sense (vision) influencing the input from another sense (hearing). This video demonstrates and explains this fascinating audio-visual illusion.
