The impact of noise Sound is all around us; with a distinction to be made between the sound we want and the sound we have to put up with. Sound can be functional and pleasant, but when sound becomes noise, it can be disturbing or even affecting human health. Noise can have an adverse impact on people in offices, classrooms, hospitals and other commercial buildings1), interfering with their daily activities at work or school and at home. People’s performance levels and ability to concentrate can be negatively affected by noise and it can make it harder for them to share knowledge with one...

What is noise? Noise is an unwanted sound; its intensity is measured in decibels [dB(A)] . The decibel scale is logarithmic, so a three decibel increase already represents a doubling of the noise intensity6). Duration of exposure is another important factor to determine the potential risk of noise. 6) 8 120 to 140 [dB(A)] 90 to 100 [dB(A)] 75 to 90 [dB(A)] 70 to 80 [dB(A)] 50 to 70 [dB(A)] School rooms 30 - 40 Offices 30 - 40 Open plan offices 35 - 45 35 - 50 Manufacturing workplaces, workshops Some common sounds and their decibel levels: Rock concert, jet take-off, gun shot Power tools,...

sound level (dB(A)) intensity duration time (seconds) generated sounds reected sounds Sound absorption Sound absorption7) indicates the noise and echo effect in an area and is expressed by the (weighted) α value (αw). An αw of 0.00 means no sound will be absorbed by the material; a value of 1.00 means all sound has been absorbed. Sound absorption positively affects both intensity and duration of noise.

DESSO SoundMaster® The carpet that improves acoustics In general, carpet can contribute to improving the acoustics in many environments, such as offices, schools and care homes. DESSO SoundMaster® performs even better against all acoustic measures. DESSO SoundMaster® offers an impact sound insulation value (∆Lw) up to +15 dB above the standard value10), thereby setting a new industry standard in carpet performance. Carpet in general reduces the impact of sound by between 20 and 30 decibel11). DESSO SoundMaster® achieves an improvement in sound absorption performance up to +0.15 (αw)10),...

DESSO SoundMaster sound soution Further tests performed by the acoustical engineering agency Bureau De Fonseca (based in Belgium) provided more evidence that DESSO SoundMaster® carpet tile backing helps to improve acoustics and therefore the learning environment in the classroom171. Both specialised software analysis18)191 and on-site measurements in a real classroom situation show that carpet with SoundMaster® backing achieves a shortening of the reverberation time and a reduction of the background noise in comparison to ceramic tiles and linoleum. This achievement is based on the...
