Just Another Thing To Worry About: Etymotic ER-200 Personal Noise Dosimeter
To help fuel the fires of everyday paranoia, the Etymotic Personal Noise Dosimeter will effectively help you judge how much damage your doing to your ears just by living. Etymotic’s ER-200 Personal Noise Dosimeter has two modes: one that measures and displays the amount of noise invading your ears over a 16 hour period, and a “quick check” mode that takes a 2 minute period an assess the noise damage you’d suffer over the course of an hour.
Weird ass product. For $100, it may only be worth it if you’re trying to build a case against an employer in regards to hearing impairment at such jobs as construction sites or live music venues. Ear plugs are also available.
