January / March 2018
Group Project with Shivam Bhatnagar, Lidia Dynes Martinez, Ben Greenberg, Jacob Mitchell and Ben Pheifer
The installation 'Cochlea' demonstrated the effects of hearing loss while listening to music. Cochlea creates a visualisation of an auditory experience.
HOW DO WE HEAR SOUND?
Frequency of sound heard along the cochlea in Hertz
For this project, 2 causes of hearing loss were modelled:
dB HL is a unit to measure what proportion of sound can be heard compared with perfect hearing
Max 7, a visual coding software was used to model the 2 types of hearing loss
The raw dB Hearing Levels were converted into multipliers to apply to corresponding frequencies of sound using this equation.
Noise Induced Hearing Loss
Once the audio track with the selected frequencies removed had been generated, the corresponding portions of the cochlea were illuminated.
An interface was developed for audience members to control the exhibit
- Max 7 code patches to generate the filtered audio tracks
- Hearing loss research
- Liaising with an expert audiologist
