Even the human hearing mechanism can inject distortion into the perceived acoustical signals! When we look at non-linear distortion we are focusing on the ability of the driver to produce harmonics and/or intermodulation products in amplitude/frequency combinations that were not present in the signal...
Surprisingly, there are sounds that even humans with the best hearing can’t hear.We can’t hear the sound of a dog whistle, but a dog can because dogs have a much large hearing range than humans do. Lower frequency sounds like the roar of a wind turbine are also out of the human h...
In simulated experiments, the model exhibited many features of human spatial hearing: sensitivity to monaural spectral cues and interaural time and level differences, integration across frequency, biases for sound onsets and limits on localization of concurrent sources. But when trained in unnatural ...
Moreover, impairments in FM sweep processing have been suggested to cause reading disabilities, which are not directly related to hearing ability5,6. The ability of humans to identify FM rates plays an important role in our daily social life; however, the neural mechanisms underlying FM encoding...
If you whisper a vowel you are hearing the second vowel formant. If you whisper them in order from the “brightest” to the “darkest” of the cardinal vowels: ee, eh, ah, oh, oo, you will hear the pitch descend with each vowel. All spoken or sung vowels must contain bot...
Understanding the human inner ear anatomy and its internal structures is paramount to advance hearing implant technology. While the emergence of imaging devices allowed researchers to improve understanding of intracochlear structures, the difficulties to collect appropriate data has resulted in studies conduc...
Navigation systems help users access unfamiliar environments. Current technological advancements enable users to encapsulate these systems in handheld devices, which effectively increases the popularity of navigation systems and the number of users. In i
many dimensions2D with depth from binocular vision, and color recognition along the frequency spectrum. Hearing relativeDistance/ratio between sound frequencies are easily identifiable relative to each other, but a pitch is difficult to identify (ex. melody is unchanged by transposition). ...
Following this aim, we conduct an ongoing project, where our ultimate goal is to design and develop a socially assistive robot for children with hearing disabilities in hospitals. We developed interactive robotic systems for this purpose without navigation, in our prior studies [1], [2], [3]....
All participants underwent audiometric testing consisting of presenting and confirming the hearing of a series of pure tones from 400 Hz to 8,000 Hz, in addition to linear sweeps, log sweeps, and white noise in the same frequency range. No subject reported a history of neurological or ...
