ER-200DW7 Personal Noise Dosimeter with Data Logging
Etymotic takes the cost and complication out of noise dosimetry.
Sound level meters measure at discrete times, while dosimeters measure continually over time for a more accurate estimate of risk.
- Color-coded LEDs indicate safe, borderline and high-risk exposures
- Data table and printable reports are automatically created in Excel
For WIN7 or earlier
- Compatible with Windows XP (SP2 or later), Windows Vista and Windows 7
- Compatible with Excel 2007 and Excel 2010
- Compatibility package required for Excel 2003; download here
Upgrade XP version to WIN7 version ($80)
User manual and WIN7 software CD are included.For an upgrade, complete the service return form and return your XP device to Etymotic. Chose "ER200D Personal Noise Dosimeter" from the dropdown menu and write "WIN7 Upgrade" in your reason for return.

Reading the Display: What the LEDs Mean
LED Color
The dosimeter uses color-coded LEDs to display noise dose in percent.
Yellow (Borderline): Noise dose is greater than 50% and less than 100%
Red (High Risk): Noise dose is greater than 100%
LED Flash Rate In Normal mode:
- A slow flashing LED at 12.5% means that the noise dose is at or below 12.5% (i.e., between 0% and 12.5%). A fast flash at 12.5% indicates the dose exceeds 12.5% (i.e., dose is between 12.5 and 25%)
- LEDs 25% to 4x flash rapidly when that dose level is exceeded
- For the bottom LED (8, 16, 32x):
- Regular flash: dose exceeds 8x
- Double flash: dose exceeds 16x
- Fast continuous flash: dose exceeds 32x
In QuickCheck mode:
- All LEDs are solid except the bottom LED, which flashes green to indicate QuickCheck mode.
- If dose per hour exceeds 8x the bottom LED flashes alternately red and green.
Hearing loss from loud sound affects millions of people. Noise-induced hearing loss is preventable, but most people don’t know how long they can listen to loud sound without risking hearing damage. A single noise exposure may not result in hearing loss, but permanent damage to the inner ear from noise adds up over time. The accumulation of too much noise day by day, year after year, is the determining factor in hearing loss risk. A sound level meter is a device that measures noise at a particular point in time, while a dosimeter measures sound levels for many hours and calculates the cumulative noise dose in percent.
Daily noise dose is determined by both the intensity of the sound and the amount of exposure time. A 100% dose means that a person has reached the maximum noise exposure for the day, and continued exposure to loud sound could lead to hearing loss. Ideally, hearing protection should be used before the dose reaches 100% since dose limits are based on averages, and some ears are more susceptible to noise damage than others. When the noise dose exceeds 50% a person has reached half the maximum noise exposure for the day and it’s a good idea to use hearing protection to prevent over-exposure, particularly if a 50% dose reading is reached early in the day.
In cases of gunfire and other impulse noise, no conventional dosimeter measures the risk accurately. More specialized equipment is required to measure impulse noise.
