Etymotic Research Wearable Personal Noise Dosimeter Model ER-200 is an important tool for accurately determining the cumulative noise dose experienced by an individual over time. Unlike sound pressure level meters which can only sample the noise level at a point in time, the Etymotic Noise Dosimeter Model ER-200 continuously measures the noise level, providing feedback to the wearer indicating the current cumulative amount of noise dosage that has been received during the time the user has been wearing the device.

Hearing damage is a function of both intensity and duration of noise experienced, making an accurate determination of whether the individual is in danger of suffering noise induced hearing loss or not, a difficult challenge in many situations. By wearing the Etymotic Noise Dosimeter ER-200, the user can be confident of his current cumulative noise dose, and receive ample warning when the cumulative noise dose begins to approach the danger level. Experts suggest that when the noise dose reaches 50%, the user should then begin using hearing protection to prevent overexposure, especially if you expect to remain exposed for additional time. Any time you exceed 100% of the daily noise dose, you are in danger of suffering hearing damage. Hearing damage is permanent and cumulative. It is not reversible, so it is a good idea to always be conservative and use hearing protection well before reaching the maximum daily noise dose.

Who Would Benefit From Using the Etymotic Noise Dosimeter ER-200?

Etymotic Noise Dosimeter ER-200 is an important component of a comprehensive workplace safety program as well as offering peace of mind to anyone who fears they may be in danger from repeated overexposure to excessive noise dosing. The following are examples in which the Etymotic Noise Dosimeter ER-200 could provide concrete feedback about the level of noise exposure:

  • A professional musician who learns that she has exceeded her maximum noise dose within a single practice session and she has not yet made it to that night's performance!
  • A music fan who discovers that his favorite clubs and concerts are giving him an extremely dangerous dose of noise that will almost certainly result in hearing damage if continued without using adequate protection.
  • The home handyman who finds that his yard work routinely exceeds his maximum noise dose before completion even though it does not seem all that loud to him.
  • The worker who fears that her workplace might not just be uncomfortably loud, but dangerously so, can get an accurate answer to her question.
  • The plant manager who has trouble enforcing the use of hearing protection devices, and can use the dosimeter ER-200 to teach his workers to understand the danger they are exposing their hearing to by failing to use the provided HPDs.
  • The manager who does not use hearing protection because he is out in the noise for just a few minutes may find that he is in more danger of hearing damage than he thought.

How it Works

Etymotic Noise Dosimeter ER-200 offers a simple color-coded readout that provides the current dosage level with just a glance.

The color coded readout on the dosimeter indicates noise doses of 25%, 50%, 100%, ER-200%, 400%, 1600% and 3200%. The indicator light remains green until the maximum daily noise dose of 100% is approached, when it turns amber. Doses above 100% are indicated by red indicator lights.

NOTE: In cases of gunfire and other impulse noise, no conventional dosimeter measures the risk accurately. More specialized equipment is required to measure impulse noise.



Etymotic Research Personal Wearable Noise Dosimeter Specifications:

"The default settings used by the ER-200 and ER-200DW7 for calculation of noise dose are consistent
with ANSI S1.25-1991 (RER-2002) Specification for Personal Noise Dosimeters."
