Other Causes of Hearing Loss
Causes of hearing loss
Sensori-neural hearing loss – permanent damage of hearing cells in the cochlea
Loud sounds 85 dB and up cause hearing loss. For every 3 dB, safe exposure time is reduced by half.
- 85 dB – 8 hours of safe time
- 88 dB – 4 hours
- 91 dB – 2 hours
- 94 dB – 1 hour
- 97 dB – 30 min
- 100 dB – 15 min (symphony)
- 121 dB – 7 sec (rock concert)

- Heavy-metal contaminants such as the low levels of lead in some drinking water
- Iron-deficiency anemia when iron levels deplete blood cells
Presbycusis – progressive loss of high frequencies hearing sensitivity associated with aging.
Age causes cardiovascular problems and other physiological issues, such as degradation of outer hair cells and the stria vascularis, mechanical changes, and stiffness of cochlear membranes.
Conductive Hearing Loss – when sound cannot go through the outer and middle ears
- Ear wax blockage
- Perforated ear drum
- Infection in the middle ear
- Issues with mobility of the three bones in the middle ear
- An abnormal growth of skin cells
- Allergies

- An abnormal growth of bone tissue in the middle ear
