Crystal-Clear Underwater Sound

Soundfish Hydrophones from Ambient bring the amazing underwater world to acustic life.

The crystal-clear, low-noise sound makes them popular with sound designers, foley artists and scientists worldwide.

Soundfish Hydrophones

Crystal-clear, low-noise sound from infra- to ultrasonic. Due to the high sensitivity and the associated enormous signal-to-noise ratio of our hydrophones, dynamics of far over 100 dB can be represented. Even the smallest sounds of a grain of sand can be recorded noise-free.

ASF-1

Our flagship hydrophone - ready for any outdoor adventure.

The ASF-1 is an extremely natural sounding, low noise underwater microphone able to capture frequencies from 7Hz to 100kHz. It is machined out of high-quality aluminum-brass and can easily withstand the water pressure of 100m depth. Additionally, sensors got encapsulated by a special polyurethane elastomer, known for its long term resistance against seawater. 

ASF-2

The smaller ASF-2 is a low-distortion microphone with a linear frequency response of 70Hz to 20kHz that combines high audio quality with excellent handling. This allows you to capture a perfect sound spectrum while effectively avoiding low-frequency noise caused by cable handling.

Due to its slim form factor, the ASF-2 is often used by sound designers and foley artists to create unique sounds.

ASF-G

A modification of the ASF-2 especially designed for underwater camera housings, such as those from Nauticam. Thanks to the included extra cable for external power supply (9V battery), the ASF-G works with any camera that has a microphone connection.

Frequency Spectrum

The Technical Center for Ships and Naval Weapons, Maritime Technology and Research (WTD 71) of the Bundeswehr (German armed forces) tested the ASF-1 MKII in September 2021. The data shows that we get very close to industry-leading manufacturers like Reson or Brüel & Kjær in terms of sensitivity over a wide frequency spectrum. The specifications here represent the average of all measured units.

Sounds by Users

What underwater enthusiasts get out of our Soundfish hydrophones ranges from impressive, previously unheard underwater phenomena to the spooky horror sounds of @freetousesounds.
