The document validates claims made about HDM® Pro hearing protection technology. It was tested using Sennheiser HD25 70Ω headphones to ensure reproduced sounds did not exceed regulatory noise limits. Claim 1 is that all sounds over 118dB are prevented. Claim 2 is sounds between 118-100dB are rapidly reduced to 100dB within 500ms. Claim 3 is the user's noise exposure does not exceed average limits set by the Noise at Work legislation, as validated by tests conducted over an 18 hour simulated day at the Institute of Sound and Vibration Research.
Noise control best practice and Best Available Technology (BAT)Peter Wilson
Examples of Self-Financing Noise Control projects across a wide range of plant categories and industries that illustrate the cost savings inherent in engineering noise control measures at source compared with conventional palliatives such as acoustic enclosures, silencers, lagging etc. In many cases, noise control modifications are installed as an extension to maintenance and can be justified simply on the grounds of increased performance, efficiency and productivity, with the noise reduction as an additional benefit. Typical noise control savings of 50-80% with no maintenance or access issues, no hygiene implications, the potential to eliminate PPE / audiometry and to remove remove existing acoustic enclosures and to improve productivity
Moore Industries is proud to announce the new SFY Functional Safety Frequency-to-DC Transmitter with display including SIL 3 capability. The 2-wire (loop-powered) SFY is ideal for use in your Safety Instrumented System (SIS) in a wide range of process and factory automation monitoring applications and as part of the FS Functional Safety Series providing reliable and accurate monitoring of frequency or pulse signals in SIS. The SFY is approved for single use in SIS up to SIL 2 and in a redundant architecture (1oo2, 2oo3, etc.) up to SIL 3.

Draeger X-act 7000 lets you precisely measure gases in the low parts per billion (ppb) range on site. It's easy to use, simply insert the Draeger MicroTubes, begin measuring, results are displayed on the display. Gas detectable are Benzene, 1,3 Butadiene, Ethylene Oxide, Formaldehyde & finally Mercury for the first time.

2. The EU Regulations
EU Directive 2003/10/EC (Noise at
Work Act in the UK) states that
employees must not be subjected
to an impulse sound greater than
137dB* or an average noise dose
greater than 85dBA* over an 8
hour period or equivalent.
*From all sources
4. Who have we consulted?
• UK Health and Safety Executive.
• ISVR at Southampton University.
• Hearing preservation charities.
• Unions.
• Insurance Companies.
• Potential end users in:
• Broadcast and live events
• Contact centres
• Industrial
• Emergency services
• Non-combat military
5. Claims for HDM®
Pro
1. Prevents all reproduced sound
over 118dB.
2. All reproduced sound between
118dB and 100dB is rapidly
reduced to 100dB.
3. Keeps all reproduced sound
below the levels defined by the
Noise at Work legislation.
6. Claim 1
Prevents all reproduced sound over 118dB.
This is a recording of the oscilloscope conducting the test
7. Claim 2
Reproduced sounds >100db* and <118dB*
are reduced in approximately 500 ms.
This is a recording of the oscilloscope conducting the test
8. Claim 3
Ensures that the users hearing dose from reproduced sound
does not exceed the regulated average for the relevant period
of time.
This challenging validation was contracted to Dr Mike Lower of
The Institute of Sound and Vibration Research at the University
of Southampton.
ISVR conducted a number of tests, including a simulated 18
hour day with exposure to different levels of reproduced sound.
HDM®
Pro monitored the reproduced sound exposure and
intervened when required to ensure that the noise dose was
below that specified for the period by the Noise at Work
legislation.
