Motorcyclists can protect their hearing with affordable earplugs. A study found soft yellow foam earplugs significantly reduced temporary hearing loss after high-speed riding, offering comfort and availability.

Area of Science:

  • Audiology
  • Occupational Health
  • Motorcycle Safety

Background:

  • Motorcyclists are exposed to high noise levels that can cause hearing damage.
  • Effective and affordable hearing protection is needed for motorcyclists.

Purpose of the Study:

  • To identify the most suitable and effective earplugs for motorcyclists.
  • To assess the sound attenuation and comfort of different earplugs.

Main Methods:

  • Three types of earplugs under £10 were tested for sound attenuation using an insertion loss technique.
  • Comfort was assessed by test subjects, with and without a motorcycle helmet.
  • The optimal earplug's effect on temporary threshold shift after high-speed riding was evaluated.

Main Results:

Related Experiment Videos

  • All tested earplugs provided approximately 15 dB sound attenuation at low frequencies under a helmet.
  • The soft yellow foam earplug was found to be the most comfortable, available, and cheapest option.
  • Wearing these earplugs abolished the temporary threshold shift (11 dB at 1000 Hz) after one hour of high-speed riding.

Conclusions:

  • Affordable earplugs offer significant protection against noise-induced hearing loss for motorcyclists.
  • The soft yellow foam earplug (EARfit) is recommended due to its cost, comfort, and availability.
