So that noise does not become a burden.
Use the athmer acoustic app to test the intensity with which everyday sound sources penetrate closed doors.
athmer acoustic app
Nowadays, many people are not aware of the impact sound and noise have on human health. This has now been proven in various studies.
With the acoustic app from athmer, you can test the intensity of your sound sources - general domestic noise, in the office, traffic noise, music, etc. - to see if they have any effect on your health.
With an automatic drop seal from athmer, you can eliminate disturbing noises and thus create a more pleasant and above all, healthier atmosphere.
Interior door
With the acoustic app from athmer, you can test at home the intensity with which your sound sources penetrate through closed doors.
A standard interior door in the living area has a floor gap (opening between door and floor) of approx. 7 mm and thus the whole door has sound insulation of approx. 23 dB. With a floor gap of 10mm, there is only 18dB left. With an automatic drop seal from athmer, you can reduce these disturbances and thus create a more pleasant and healthier living atmosphere.
A continuous sound level (longer than 0.2 sec) of 60 dB during sleep already leads to stress actions in the body, from 80 dB long-term physical damage can occur. For a quiet and restful sleep, background noise must not exceed 40 dB.
Below are a few examples of which everyday sounds produce how much dB:
Jet 130dB
Aeroplane at close range 120dB
Traffic noise (distance building to road/car approx. 7m) 70dB
Normal conversation 50dB
Usual sounds in the apartment 45dB
The pain threshold of the human auditory system is 130 dB. Noise exposure of 150 decibels causes irreparable damage within seconds.
Glossary
Sound
Mechanical vibrations and waves in an elastic medium, e.g. airborne or structure-borne noise in the human auditory range. If sound lasts longer than 0.2 seconds, it is referred to as continuous sound. Sound waves are generated when speaking or making music, among other things, but are also produced as noise from, e.g. machines.Noise
Any type of sound, especially of high intensity that disturbs annoys or even damages a person's health.Decibel (dB)
Defines the intensity of sound. A decibel is a logarithmic unit: this means that to obtain an increase of 10 dB, the sound source must be increased by a factor of 10. The human ear would perceive this as about "twice as loud".Note: The result of the sound measurement in this app cannot be compared to a professional measure. The result is only a rough guide. An exact measure is not possible due to the inaccuracy of the microphone and the unstable background noise.
