How Hearing Works

Watch this video for an overview of the anatomy of the ear and how we process sound in order to hear.

Please note that 85 decibels or A-weighted decibels (dB or dBA) derives from the National Institute for Occupational Safety and Health recommended exposure level for occupational noise. (A-weighting adjusts sound measurements for the frequencies heard in human speech, and is used by NIOSH because the inability to hear speech is the compensable workplace injury from occupational noise exposure.)

As such, 85 dB or dBA is not a safe noise exposure level for the public. It does not prevent noise-induced hearing loss or other auditory injury in workers, and cannot be applied to sensitive populations like children, the elderly, or pregnant people. The only evidence-based safe noise exposure level is a time-weighted average of 70 dB daily, and the actual safe noise exposure level may be much lower.

"Who is the owner of your eyes and ears, the most precious of your members? From which workbench or shop did you obtain them? It is only your Sustainer that could give you them. It is He Who creates and raises you, and gave you them. In which case, there is no Sustainer but He, and the only one fit to be worshipped is He."
Words - 429, by Said Nursi, (Qur'an, 10:31-2.)

We have a creator. Believing this happened without any thought behind it is absurd. Our creator - the God of Abraham Isaac and Jacob designed us.
