This is a recording of a Samsung (AE080RXYDEG) air source heat pump. Follow the instructions below (also available as a PDF) to set up a Bluetooth speaker at the right volume so you can test out different positions. A speaker is also included as part of the frame kit. Or just click play on the audio player to get an idea of the sound.

Speaker instructions​

Bluetooth speaker

• The Bluetooth speaker provided
• A smartphone or tablet

Sound meter download

First you will need to download a sound level meter app to you phone or tablet. Search for and download the app called “Sound Meter” (by Abc Apps) from either the App Store or Google Play.

Find a quiet place with as little background noise as possible.

Turn on the Bluetooth speaker and connect to it via Bluetooth using your phone or tablet – it is called “SPEAKER 5.0”.

Start the audio player. You should hear the sound playing from the Bluetooth speaker. It will repeat until you pause or stop it. If your phone/tablet stops playing when you switch to another app, you may need to play the sound from another device to do the next step.

Sound meter
Now bring up the Sound Meter app. Hold your phone/tablet about 1m (3 feet) away from the front of the Bluetooth speaker, with your phone/tablet microphone angled towards the speaker. Use your phone/tablet volume control to turn the sound up or down until it is steady at around 50 dB (or if you have a specific model of heat pump in mind, check the manual to find out its decibel rating).

You are now ready to position the speaker. Put it where you are thinking of having your heat pump installed (you could stand it inside the Test Drive frame, if you have one).

It should give you an idea of what the sound might be like. Remember that your pump will be running most during winter, so you might want to check it from inside you house, with and without the windows open. Also consider neighbouring properties.


Please note that the speaker is unable to reproduce the exact sound an actual pump might produce, and that sound levels and types differ for different pumps. So this is just to act as a basic guide. For more on the pump recording included above, see this useful Earth Notes article.
