New MOLES environmental noise monitor from Svantek

Svantek's MOLES system

Miniature Outdoor Logging of Environmental Sound system operates for up to four weeks on single charge

FURTHER underlining their commitment to reducing the impact of noise on the environment, Svantek UK Ltd have launched the MOLES (Miniature Outdoor Logging of Environmental Sound) system, a low-cost yet powerful new outdoor noise-monitoring solution that can, depending on temperature, operate for up to four weeks on a single charge.

Using Svantek’s Class 1 SVAN 971 sound-level meter and featuring a robust, weatherproof and compact design to IP65 protection level, the MOLES is a fully autonomous environmental noise-monitoring solution that can be easily deployed in the field.


Lightweight and long-lasting, the MOLES’ internal batteries can be swapped without interrupting measurement, while external batteries can be added to extend life to eight weeks or more.

Svantek’s new MOLES system is available with options for 1/1 and 1/3 octave real-time analysis and triggered audio recording. It also offers two in 10 audio recording, making it suitable for measuring levels of noise from wind turbines.

John Shelton, managing director of Svantek, said: ‘The MOLES is based on our diminutive and well-proven SVAN 971 instrument. It is an integrated kit with long-term rechargeable battery and outdoor protection for both meter and microphone.

‘Extremely cost-effective, it is perfect for independent environmental noise assessors or larger consultancies, and reinforces Svantek’s aim of developing high-performance solutions that offer real value for money.’

Svantek’s MOLES is available with free SvanPC++ software with the option of environmental calculations/tonal assessment. MOLES provides 4GB storage capacity and data can be stored on an easily downloadable micro SD card.

Svantek’s SVAN 971 sound level meter is designed for general acoustic, occupational health and safety, and environmental noise measurements. Incorporating a bright and sharp OLED colour display, it is easy to use with predefined set-ups and operated using a simple stop/start mode.
