Traceable calibration refers to the process of verifying and adjusting the accuracy of a measuring instrument or device using a known reference standard that is directly traceable to a national or international measurement standard. The purpose of traceable calibration is to ensure that the instrument’s measurements are reliable and consistent,…

by Aidan Hubbard, Sales Director The world is now filled with badly designed and cheap products, ranging from audio equipment to kids toys, vehicles and machinery. As a consumer you are typically guided by one main thing, this piece of information is usually the first thing and the last thing…

By John Shelton, Technical Director and Chair of IOA M&I Committee Sometimes it’s difficult to keep up with the innovations in noise and vibration technology, and over the past 50 years or so, we have moved from van-sized analogue analysers to hand-held multi-function digital devices. A large part of these…

Traceable calibration and UKAS calibration both aim to establish the accuracy and reliability of measuring instruments, but there are some key differences between the two. Here are some benefits of traceable calibration over UKAS calibration: Cost Traceable calibration is generally more cost-effective compared to UKAS calibration. UKAS (United Kingdom Accreditation…

Svantek UK have recently supplied the University of Salford 10 SV 971A Class 1 sound level meters, for students on the Environmental Noise Measurement and Modelling Module. This module is delivered to level 6 and 7 acoustic students with the new addition, this year, of level 7 sustainable aviation students.…

Sound level meters are also known as noise meters, decibel meters, or dB meters.  Following BS EN 61672, noise level meters are composed of a microphone, a preamplifier, a signal processor, and a display that displays noise results. Hand-held noise level meters are usually battery-powered and feature a triangular tip and windscreen on top. A sound level meter is a…

The SV 803 has the power of a PC based instrument and all compacted into a solution that is no larger than a sandwich box! PC based solutions have been the saviour of many consultants over the years but they are bulky and rely on interconnecting cables and expensive sensor…

When I look at the spec sheets for microphones and sound level meters, I see reference to Dynamic Range, Measurement Range and Linearity Range. Surely these are the same, or am I confused? They are completely different definitions, although measurement range and dynamic range are often used interchangeably: Dynamic Range…

How do I set the feet of the tapping machine, so it fulfils the standard? The EOS is built and adjusted at the factory so the hammer drop meets the ISO standard (40mm +/- 5%). If you subsequently have the machine laboratory calibrated, this will be checked and certified, along…
