Sensaphonics introduces dB Check IEM level analyzer

In-ear monitoring specialist Sensaphonics Hearing Conservation has introduced the dB Check in-ear sound level analyzer. The device is designed to accurately measure sound pressure levels with the earphones inserted. Designed to work with Sensaphonics custom earphones, the dB Check is an in-line device that measures and displays the actual A-weighted SPL along with the recommended safe exposure time for that level on both the NIOSH and OSHA scales.

The dB Check plugs in between the sound source (IEM bodypack, iPod, etc.) and the earphones. The user selects the Sensaphonics model being used, sets the duration (1-120 minutes) and monitors normally. In operation, the dB Check displays the A-weighted decibel level in real time. When the duration expires, the LCD display shows both the average SPL and the recommended daily exposure time under both NIOSH and OSHA guidelines.

While it is commonly believed that the use of personal monitors helps artists to listen at lower levels, a recent Vanderbilt University study shows that, in practice, most musicians tend to turn up their IEMs to the same levels they are used to enduring with floor wedges. “The problem is, old listening habits die hard,” said Michael Santucci, Sensaphonics president and a practicing audiologist. “As a result, many well-intentioned IEM users are monitoring too loudly without knowing it. DB Check is the only device that addresses this issue. It can’t force you to turn down the volume, but it gives the information needed to make an informed choice.”

Additional functionality built into the dB Check includes a condenser microphone for taking room-level measurements. The unit is powered by a rechargeable lithium-polymer battery and ships in a rugged Pelican case. Supplied accessories include an audio interconnect cable and USB charging cable.
