Dual SPL Traffic Light

Dual SPL Traffic Light is an SPL monitor, designed to be used to monitor SPL levels for live concert sound, community noise, and any public space that needs to be in compliance with sound level regulations. Use Dual SPL Traffic Light with the built-in iOS device microphone, or pair it with our iTestMic for Class 2 results, or use it with our iPrecisionMic for Class 1 performance. Note that it is possible to certify the entire instrument as Class 1, by sending iPrecisionMic and your iOS device to an independent testing lab.


Available in AudioTools on the App Store

 

See our new White Paper on the Dual SPL Traffic Light.

Having two sound level monitors allows Dual SPL Traffic Light to adapt to nearly any community noise standard regulation, since you can set one meter for C weighted Fast, and the other for an Leq (average) time. The example here shows exactly that setup. This flexibility makes our Dual SPL Traffic Light the most versatile SPL monitoring system available on any platform.

 



The top control selects which SPL monitor the settings apply to. Enter the dB trigger levels for the three colors, and select the weighting or octave band.

You can also enable email notifications, based on the display criteria for the red dB trigger level. Notifications can be based on just one SPL monitor triggering into the red zone, or either or both triggering. Enter your own gmail credentials for the email notification server. Note that Google’s policies may require you to go to your own gmail settings, and enable access from a third party app.

Set the three color trigger dB levels, dynamic response, and weighting seperately for each SPL monitor.
