Frequency
Frequency is the number of oscillations/pressure variations in a given time period. The unit of frequency is Hertz (Hz), where 1 Hz corresponds to one oscillation cycle per second. The human ear can perceive frequencies between 16 and 20,000 Hz. A low tone is produced by slowly oscillating sound waves. The faster the oscillations, the higher the sound perceived.
Room noise
In interior spaces, sound waves are reflected from walls, ceilings and floors. This creates a diffuse sound event consisting of superposed sound waves propagating in all directions.

Sound insulation
Sound insulation is the acoustic shielding of a room or device in order to prevent or reduce the transmission of air-borne or solid-borne sound to neighboring spaces. The aim is to prevent the sound from propagating by using sound insulation materials to build a sound barrier around the noise source.
Noise control
Equipping the room with noise control materials reduces the sound level (and hence the perceived noisiness) and improves speech intelligibility. Such an improvement of acoustic conditions makes for a much more pleasant atmosphere. Porous and fibrous materials such as open-cell foams or non-wovens are excellent sound absorbers. But also closed-cell foams with a special cell structure, for instance our soni RESIST, score with good sound absorption capacity.
