The Ambient Noise feature allows you to monitor the test environment for noise during audiometric testing. It is ideal when testing in non-optimal conditions or when testing via tele-audiometry.

Knowledge of your testing conditions will allow you to assess the validity of your measurements ahead of making a diagnosis.

Ensure that you have the Ambient Noise microphone plugged into your Equinox Evo. The socket for this has been highlighted in the image below.

Launch your Equinox Evo Suite and go into the AC440 Module.

The Ambient Noise monitor can be seen in the left panel of the AUD screen when enabled in your test protocol.

The Ambient Noise feature constantly shows the average noise level in the top bar and then individual frequency levels below. It will show darker bars (limits) and orange bars above this when the limit is exceeded, see example below.

The Ambient Noise feature operates according to specific guidance found in calibration standard documents. The applied settings can be found in the configuration of this feature in your protocol settings.

Ambient Noise is located in a tab called Common. The user has the following options. Toggle Ambient Noise to be active or inactive. Use ANSI, OSHA, ISO, or Custom standard. Set the dB limit per transducer at individual frequencies.

Toggling between the ANSI, OSHA, ISO, or Custom standards auto-populates the dB limit per transducer at individual frequencies.
