Health & Safety Comprehensive Course Calendar
To help industrial engineers meet increasingly strict acoustic requirements, Bruel & Kjaer (UK) has added a new noise and vibration control training course for 2013.
These acoustic requirements are imposed by more stringent regulations and can only be met by considering noise and vibration control as an integral part of the product creation process, which in turn puts tremendous pressure on the industrial design engineer. The three day Noise & Vibration Control
course gives engineers a thorough understanding of the basic concepts that are important for airborne - and structure-borne - noise and vibration in machinery.
Bruel & Kjaer UK’s other training sessions for the New Year includes the Theory and Practice of Noise Measurement course. This two day session provides a good, basic understanding of acoustic and measurement principles, covering many applications such as noise abatement, product labelling and building acoustics. Attendees will learn to carry out a host of noise measurements, correct set-up of measuring instruments and assessment of noise reports.
There is also the Vibration Testing for Engineers and Technicians course which provides a practical introduction, explaining how to interpret vibration test specifications and apply them to a vibration test system. It’s designed for engineers new to the field of vibration testing, but also acts as a useful refresher for more experienced users.

Acoustic Calibrator Achieves Germany's PTB Approval
Casella CEL (UK), global specialist in industrial hygiene and occupational health monitoring equipment, has announced that its compact CEL- 120 acoustic calibrator has recently achieved Physikalisch-Technische Bundesanstalt (PTB) approval.
The PTB is Germany’s National Institute for Natural and Engineering Sciences and is the country’s highest technical authority for metrology, similar in standing to the UK’s National Physical Laboratory (NPL).
Launched a year ago, the CEL-120 is believed to be one of the world’s smallest acoustic calibrators and is designed to facilitate the highly accurate calibration of Sound Level Meters in the field.
Casella’s CEL-620 Sound Level Meter is already similarly approved and will now benefit from being paired with the CEL-120 making it ideal for workplace noise monitoring.
Ben Henson, Casella Measurement’s General Manager comments: “The CEL-120 sailed through the raft of testing without a hitch and we were never in any doubt that we would get the approval.”
Type approval, although not required in the UK, is also ‘on the agenda’ in Spain where the Measuring Instruments Directive 2004 is locally implemented to include noise measuring instrumentation.
Testing included checking the acoustic and environmental performance against the requirements of IEC 60942:2003.
Calibration is an essential procedure when conducting any type of noise survey both before and after each measurement sequence. The process ensures that instruments are providing consistently precise readings necessary for monitoring to ensure compliance with workplace and environmental noise regulations.
Fully compliant with IEC 60942:2003 and ANSI S1.40:2006 standards, Casella’s new CEL-120 acoustic calibrator, which measures just 75mm x 54mm x 37mm, incorporates the latest digital technology to ensure exceptionally stable acoustic performance, as well as dual calibration level (Class 1 version) of 94dB and 114dB at 1khz.
For added ease-of-use benefits, the CEL-120 features a simple keypad for intuitive control, permitting calibration level changes as required. When used with instruments such as Casella’s well proven CEL-620 series of sound level meters, calibration routines start automatically as soon as a calibration tone is detected.
A MEMS (MicroElectrical-Mechanical System) microphone and a digital feedback loop maintain the acoustic pressure in the cavity at the required level. An indicator shows if the sound level meter microphone is incorrectly inserted into the cavity, A MEMS (MicroElectrical-Mechanical System) microphone and a digital feedback loop maintain the acoustic pressure in the cavity at the required level. An indicator shows if the sound level meter microphone is incorrectly inserted into the cavity, removing any potential for calibration error. An energy-saving automatic power off function helps ensure batteries last for up to two years.

A Range of Health and Safety Measurement Solutions
The CVK hand arm and whole body vibration dosemeters record levels using a wireless safety glove or seat pad. In-situ measurements ensure optimum accuracy on one or both hands simultaneously. Vibration exposure is instantly visible via a wireless LED indicator. The kit features 12 hours battery life, wireless connection and full post- processing software for simple and accurate assessment. For use in harsh conditions the kit is water resistant as standard.
The Nor-131 &132 hand held sound level meters meet all HSE & Noise at Work 2005 guidelines. The simple to use meters record the effectiveness of hearing protection devices, to ensure staff are fully protected at all times, and the NorProtector specialist software exports the results to Excel.
SoundEar warning signs provide a very clear indicator of noise exposure via an amber/green/red light warning system. They are wall mounted and can be mains or battery operated. The system meets Noise at Work 2005 regulations.
