Reviewers say the following about shopping for earplugs:

  • Consider their primary use. If you're constantly exposed to loud sounds -- either because of your hobby or because of your job -- look for earplugs that aren't easily dislodged, such as Howard Leight MAX (which expand inside your ear canal when inserted). Otherwise, looser-fitting foam earplugs may be a better choice.
  • The loudness of a sound is measured in decibels (dB). Decibels work on a logarithmic scale, which means that a reduction of 10 decibels is roughly equal to reducing the loudness by half. A reduction of 20 decibels roughly equals a perceived reduction in loudness of 75%.
  • Pay more attention to comfort than NRR. Although an earplug's Noise Reduction Rating (NRR) is important, it doesn't count for much if the plug is uncomfortable. Ratings of 28 to 33 decibels are fine for most ordinary uses; the two earplugs in ConsumerSearch Fast Answers, Howard Leight MAX and Hearos Ultimate Softness, have ratings of 33 and 32 decibels, respectively.
  • Consult an audiologist -- or your employer. If you're unsure about which earplugs are best for your needs, an audiologist should be able to give you a good recommendation. Also, if you have a noisy work environment, your employer may be legally obligated to supply you with effective earplugs.
