Background:
2
Noise exposure can lead to hearing loss and multiple system dysfunctions. As various forms of noise exist in our living environments
and our auditory organs are very sensitive to acoustic stimuli
it is a challenge to protect our hearing system in certain noisy environments.
Presentation of the hypothesis:
2
Herein
we propose that our hearing organ could serve as a noise eliminator for high intensity noise and enhance acoustic signal processing abilities by increasing the signal-noise ratio. For suprathreshold signals
the hearing system is capable of regulating the middle ear muscles and other structures to actively suppress the sound level to a safe range.
Testing the hypothesis:
2
To test our hypothesis
both mathematic model analyses and animal model studies are needed. Based on a digital 3D reconstructed model
every structure in the auditory system can be analyzed and tested for its contribution to the process of noise reduction. Products manufactured by this bionic method could be used and verified in animal models and volunteers.
Implications:
2
By mimicking the noise-reduction effect of the sophisticated structures in the hearing system
we may be able to provide a model that establishes a new active-sound-suppression mode. This innovative method may overcome the limited capabilities of current noise protection options and become a promising possibility for noise prevention.
