What do we hear how loud?

When a noise becomes noise

A sound is heard and vibrations, known as sound waves, are created, which the human ear perceives. The volume of these waves is measurable and is given in decibels (dB). As the decibels increase, so does the sound pressure, which becomes a burden for the human ear. This burden is indicated in the unit dB(A). 

People find sounds from 40 to 65 decibels pleasant. Sounds over 65 decibels are unpleasant and cause stress in the ear and consequently in the whole organism. If we have to endure the noise permanently, we become ill. A sound level of 85 dB can already cause lasting damage to the human hearing. 

Sound waves from 95 dB are almost unbearable for humans in the long run. We perceive 120 decibels and more as painful. 

An agreeable and quiet room climate can be achieved not only through low decibel levels. At Variotherm, there is a system with the ModularCeiling-Acoustics that can heat and cool while also offering an acoustic function. This not only improves thermal comfort but also acoustic well-being – ideal for office, living, or classroom spaces where low noise levels and high concentration are important.
