Frequently asked questions.

What is 'sound'?
Sound is the vibration of molecules (medium air, water or solid material) generated by a sound source. Due to resistance of medium, these molecules move in waves. These vibrations are picked up by the ear / eardrum and perceived as sound by brain. Sound is affected by factors such as reflection, scattering and absorption when moving through a room.
Triplacoustics products provide both reflection, scattering but especially efficient absorption of incident sound. -
What is frequency (Hz)?
Number of vibrations per second measured in Hz. It determines the pitch of sound. Higher frequencies mean higher tones perceptible.
For Triplacoustics products, the frequencies between 50Hz and 5000Hz are structurally relevant. -
What are octave bands?
Octave bands are frequency bands used in acoustics to analyse the frequency spectrum of sound. These octave bands are useful for assessing sound quality and speech intelligibility in different environments.
Triplacoustics' acoustic reports show the third- Octave bands, as obtained during reverberation chamber testing lab, for all products on the technical datasheets. -
What is a sound wave?
A sound wave is a longitude wave, namely air particles moving back and forth in the same direction as propagation direction wave.
Triplacoustics products are efficient absorption panels for human speech, producing sound waves at speeds of 343metres per second, with pitches relevant between 250 and 5000 Hz. -
What is sound pressure and decibels?
Sound pressure refers to the variation in air pressure caused by a sound wave relative to atmospheric pressure, measured in Pa (pascals). The sound pressure level, expressed in dB (decibels), is a logarithmic measure of this sound pressure. For the human ear, this ranges from the hearing threshold at 0 dB to the pain threshold at 130 dB.
At Triplacoustics, we focus more on sound absorption than sound insulation. While terms such as sound pressure and decibels are relevant to insulation products, our expertise lies in improving acoustic quality through advanced absorption panels. Our products are designed to minimise reverberation and echoes, creating a more comfortable and peaceful indoor environment.

Functioning human hearing?
The human ear is a complex organ that captures sound waves, converts them into nerve signals and sends them to the brain, where they are perceived as sound.
For Triplacoustics products, the improvement of speech intelligibility in an indoor space is central. By correcting reverberation in a room, the comfort of a person with a poorly functioning human ear can still be greatly improved.
