How do I view LAeq1s measurements in the Noise Guide measurement library?

Posted Sep.19th 2017:

As a standard, the Noise Guide software can only show you LAeq1min in the measurement library but there is a small work around in order for you to view your measurements as LAeq1sec.

See this tutorial video on YouTube in order to find out how.

How big is the internal memory on your devices? And on your USB drives?

The internal memory of a SoundEar device is 16 MB.

The SoundEar USB drives have a memory of 8 GB.

What are the different features of the SoundEar 3 software?

To get an idea on the different functionalities of the SoundEar 3 software watch this demonstration video on YouTube

Why can’t I download my SoundEar 3 or Noise Guide measurements to the USB drive?

Make sure the USB drive is formatted (FAT 32) before using it, and make sure the USB drive is empty, before inserting it into your device.

Why is my SoundEar 3 device not connecting to the SoundEar software?

The first time you connect your SoundEar 3 to your PC, Windows Update will try to find a driver for the software (this may take a while – around 5 minutes) – after this, Windows will “give up” and install a standard HID driver.

When the driver is installed, the device should connect to the software. You can check in your ‘Device manager’ in Windows to see if the ‘HID compliant system controller’ is installed – this would be your SoundEar 3 device.
