Sound Level Research
Threshold of hearing : The standard threshold is taken to be at 0dB but the measured human threshold of hearing is 1000Hz which is 4dB. The maximum sensitivity is around 3500 to 4000Hz.

Threshold of Pain and Discomfort : Sounds above 90dB can cause hearing damage if someone is exposed to it every day. If the sound level is above 130dB it starts to hurt because 130dB is the threshold of pain. If it is above 110dB it surpassess the threshold or discomfort. hearing, H. (2019).
