Description

Dual SPL Traffic Light Monitor sound levels for events, public spaces, and concerts. Two independent sound monitors allow you to configure this app to any local requirements. For example, set one traffic light to average SPL over 10 minutes, and set the other to monitor peak levels. Set one to A weighting, and the other to C weighting, or flat. This app works fine with the internal iOS device mic. You can also upgrade to our iPrecisionMic or iTestMic to get Class 1 or Class 2 results. Each traffic light can be linked to a color light bulb using HomeKit, to provide visible notification of sound levels. Place a color light bulb near the sound mixer, stage, or even the manager's office, so that everyone can see if the sound levels exceed your preset trigger levels. Set the SPL decay (speed and type of averaging) to Fast, Slow, or any Leq value from 1 second to 8 hours. The Leq can be done one time period at a time, or it can be a running Leq of the last time period. Set the SPL weighting to flat (Z), A, C, or one of the low frequency octave bands, 32Hz, 63Hz, 125Hz, or 32Hz+63Hz. Includes email notifications for sending emails when either or both meters is triggered into the red level.
