In spring 2020, GRAS Sound & Vibration joined the Battery Ventures’ portfolio alongside US-based Audio Precision, bringing together two great brands into one platform

As part of bringing these two brands together into one of the world’s strongest portfolios for acoustic sensors and audio measurement, we are now offering all GRAS products through Audio Precision UK Ltd, alongside our AP audio testing suite within the United Kingdom.  


We are incredibly excited to continue supplying our customers with market leading measurement microphones and equally enthusiastic to help new engineers and technicians via collaboration with Audio Precision.  We will remain at the forefront of your acoustic testing requirements and welcome the opportunity to continue to meet your application needs.

For reference, your local UK GRAS and AP contacts are:
