NOTES:
* The brass section playing fortissimo can drown out practically the whole orchestra.
* One-third of the total power of a 75-piece orchestra comes from the bass drum.
* High frequency sounds of 2-4,000 Hz are the most damaging. The uppermost octave of the piccolo is 2,048-4,096 Hz.
* Aging causes gradual hearing loss, mostly in the high frequencies.
* Speech reception is not seriously impaired until there is about 30 dB loss; by that time severe damage may have occured.
* Hypertension and various psychological difficulties can be related to noise exposure. * The incidence of hearing loss in classical musicians has been estimated at 4-43%, in rock musicians 13-30%.
