DEFINITIONS

A decibel (dB) is 1/10 a bel, a bel was originally a measurement of sound loss in telephone cables and so-named after Alexander Graham Bell.  The scale is not linear but logarithmic.  For example, a sound that is 10dB louder than another is in fact twice as loud, a difference of 15dB is three times louder.  Therefore a sound reduction of 10dB will seem half as loud as before.

Rw is the weighted sound reduction index in decibels (dB).  In the laboratory, our doors are tested at different frequencies, the best reduction has been measured at 57dB at 6300 hrtz, but when averaged out across all the readings the same door is given a rating of 48dB.

Rule of Thumb e.g. a 36dB Rw doorset provides double the performance of a 33dB Rw doorset.

Our Acoustic Doorsets have gained Quiet Mark Approval

We are pleased to announce that our bespoke flush acoustic doorset systems have received the Quiet Mark accreditation.

The Quiet Mark is an initiative from the Noise Abatement Society which aims to counteract the stressful effects of noise in our everyday lives.

The Quiet Mark, which is a distinctive Q-logo, is awarded to products that promote “quietness”.  An example of this would be a manufacturer who develops a quieter hair-dryer.

The Quiet House was a unique concept which was trialled at the Ideal Home Show, earlier this year.  Inside the Quiet House, we showcased the effectiveness our acoustic doorsets in cutting out excess noise.  Other appliances and fittings were also demonstrated, to show how a quieter and more productive domestic life could be achieved.

The Quiet House was recently featured in the BBC programme, Click which showed how alternative and quieter products can enhance our lives.  The programme was widely broadcast across the BBC and shows just how important the quest for a quieter life has become.
