Can low frequency hearing loss be corrected?

Conductive hearing loss is called such because sound is not being conducted to the inner ear properly. Generally, it effects low frequencies first and can progress to affect all frequencies. Fortunately, most conductive hearing losses can be treated medically with little or no long-term effects on the hearing.

How loud can a human yell?

The loudest (verified) human scream was 129 dB (decibels) performed by Jill Drake, a woman. In contrast, the average lawnmower is around 90 dB, a jet engine around 120 dB and a gunshot around 140 dB. Any exposure to decibel levels at or above 140 dB can cause immediate hearing damage.
