It is estimated that 50% of those listening to music over their personal audio devices do so at levels that put their hearing at risk

  • Those exposed to loud sounds in social settings over the past 20 years are over three times more at risk of hearing loss compared to those unexposed.
  • 50% of people listening to music over their personal audio devices do so at levels which put their hearing at risk.
  • 5–10% of listeners are likely to develop hearing loss due to their personal volume preferences and duration of listening.
  • Depression, isolation, frustration, cognitive decline and decreased personal safety are twice as common among seniors with hearing loss than those without hearing loss

PREVENTION

Regulating exposure to loud sounds through personal audio systems

Acoustic dosimetry

Tracking users’ exposure time to sound

  • Estimating sound level
  • Estimating % used of a reference exposure, or sound allowance
  • Mode 1: (WHO) standard level for adults. This Will apply 1.6 Pa2h1 per 7 days as the reference exposure (i.e. 80 dBA SPL for 40 hours per week).
  • Mode 2: (WHO) standard level for sensitive users (e.g. children).

This will apply 0.51 Pa2h per 7 days as the reference exposure (i.e. 75 dBA SPL for 40 hours per week).

Volume limiting

  • Volume limiting message
  • “Continue listening” option
  • Default action: to reduce the volume output to a predetermined level
  • Customizing option

Parental control 

  • Maximum sound output can be fixed and locked in the device’s settings

messages

  • Noise-induced hearing loss is irreversible!
  • Prevention is one of the most effective strategies to reduce the occurrence of noise-induced hearing loss.
  • Keeping the volume within safe levels and limiting the time spent engaged in noisy activities can reduce the risk of hearing loss.
  • Smartphone technology can be used as a means to promote and practice safe listening.
  • The design and implementation of specific legislation can lead to a lower level of sound exposure
