A Sound Level Calibrator is used to produce a known sound pressure level. It is a hand-held device that emits an audible tone of very accurate level and frequency. Typically the calibrator is fitted over the meter’s microphone and the reading is either checked manually by the user or automatically…

Sound Power is the ability of a device to make sound. It is purely a function of the device and unable to be measured directly. It has units of watts, and in decibel terms, dB re: 1pW. The sound power is radiated into the acoustic field by sound intensity, a…

History There’s nothing like moving house or office to unearth some old project from the past, and while unloading all my shelves of documentation, I happened upon an old presentation I put together more than 20 years ago when I started AcSoft. Lovingly crafted on overhead transparencies using Word Perfect…

There are numerous noise sources in ports and waterways, including horns, whistles, signals, terminal operations, engines, construction and logistics. As well as ensuring compliance with environmental noise regulations, operators must minimise, mitigate or reduce noise from both essential processes and other sources. As a result, monitoring the impact of sound…

Our extremely compact SV 110 hand-held vibration calibrator is designed for verification of machine sensors, as well as on-site checks of human vibration accelerometers, to ISO 8041. Faults caused by transverse vibrations are indicated by two LEDS on the calibrator’s housing. This unique solution ensures stability of both the calibration…

Its now been a year since AcSoft setup its own noise and vibration calibration laboratory and our offering has grown from strength to strength. Our lab is run by Alex Santana who qualified in acoustics in his home city of Las Palmas de Gran Canaria (although we don’t know why…

The Menhir (Modular Enhanced Intelligent Recorder) ground vibration monitor from Semex-Engcon GmbH is a very compact and versatile instrument that measures vibrations, shocks and tremors making it perfect for use in trackside monitoring applications. It has options for MEMS accelerometers, geophones and even an FBA force balanced accelerometer that is highly sensitive and…

We’re delighted to announce that Jacek Kuczynski from our head office in Poland will be presenting a technical paper titled “IMPROVED METHODS OF ASSESSMENT OF WHOLE-BODY VIBRATION RISK IN MOVING VEHICLES” at the “50th UK Conference on Human Responses to Vibration” at the Chilworth Manor Hotel in Southampton in September.…
