@article{Behar_2006, title={Impulse noise hazard - What do we know about it?}, volume={34}, url={https://jcaa.caa-aca.ca/index.php/jcaa/article/view/1800}, abstractNote={The auditory Harard Assessment Algorithm for Human (AHAAH) was created to define impulse noise and to provide a tool that would make an assessment of the hearing hazard from impulse noise levels above 150 dBPeak. A mathematical model of the entire ear, including the external, middle, inner parts, muscles, and bones was created. The ultimate receptor of noise, the basilar membrane was divided into 23 locations, in the model. It was found that the basilar membrane oscillates, when the impulse is entered in the model. The upward flexes for each of the 23 locations were tracked, their amplitude in microns was squared, and the sum for each location was maintained. The model operated on a personal computer (PC) in WINDOWS environment and the waveform of the signal to be assessed, was entered in the program as an ASCII file. The AHAAH method has been tested in animals and validated in human and was found to be correct in 95% of the tests, with protected hearing.}, number={3}, journal={Canadian Acoustics}, author={Behar, Alberto}, year={2006}, month={Sep.}, pages={16–17} }
