To determine the resonance lengths of a given frequency sound using the Resonance Apparatus (RES-APP), we recommend the following:
- Go Direct® Sound Sensor (GDX-SND) (use the Sound level C-weighted channel)
or - Sound Level Sensor (SLS-BTA)
In order to relate the speed of sound to the air temperature, consider a temperature sensor. We recommend a surface temperature sensor for its fast response.
- Go Direct® Surface Temperature Sensor (GDX-ST)
or - Surface Temperature Sensor (STS-BTA)
