Washington — NIOSH has released an updated version of its free Sound Level Meter app, designed to measure noise exposure in the workplace.
The update includes new information on how to conduct a noise survey and select proper hearing protection. The agency also has improved the app’s help screens, NIOSH announced Jan. 23 via Twitter.
Along with sharing and reporting data, the app has the capability to calibrate an internal or external microphone.
The NIOSH Sound Level Meter is available to download from the Apple App Store. For Android users, the agency states that because of the large number of available Android devices and models, “testing and verification of the accuracy and functionality of an Android-based app in our laboratory is not currently possible.”
