Stop Noise Pollution - Double Glazed Windows from Paarhammer

Double Glazed Windows from Paarhammer

With all the hustle and bustle in our daily life we crave peace and quiet in our homes. But noise from roads, planes or neighbours disturb our well-earned relaxation time. Stop the noise and create a quiet oasis with Paarhammer windows and doors!

Noise is accepted to be the fastest growing type of pollution in modern cities, and its effect on our mental and emotional health has a direct influence on our physical well-being, everything from lack of sleep to increased stress, heart attacks and strokes. Our health suffers if there is a constant noise level and our bodies and brain cannot regenerate.

We need sound to communicate and unexpected noise may warn us of danger. Sounds we hear tell us a lot about our surroundings. Frequency, wavelength, pressure and speed of sound all have an influence on how we perceive it.

Sound pressure level (sound intensity) is measured in decibel (dB), a logarithmic unit. Each 10dB increase is an increase of sound by ten times, e.g. a sound at 20dB has ten times more energy than at 10dB. And a sound at 30dB has 10x10 (so 100 times) more energy than at 10dB. Or maybe an easier way to calculate: every 3dB increase is approximately a doubling of the sound intensity or acoustic power.

But our ears hear sound differently. The normal range of hearing extends from 0 dB (hearing threshold) to around 130 dB (pain threshold). A difference of 10 dB halves / doubles the noise, e.g. if the sound pressure level was increased by 10dB then we would feel that the sound was twice as loud, so a noise increase from 60dB to 70dB would seem to have doubled. If it was reduced by 10dB then we would feel that the noise had halved so a decrease from 60 to 50dB.
