- The problem is not the noise level. It is a pressure difference
- sustained for longer than the lowest perceptible frequency which will
- perforate a drum, in conditions when there is some impediment in the
- Eustachian tubes, such as catarrh due to a cold. For example, it is
- possible to suffer eardrum perforation when descending in an
- aeroplane. I hope most airbag designers know more than you do about
- what is involved in ear damage.
