Understanding the terminology behind acoustic technology. A comprehensive guide to industry terms and concepts.
An engineered material designed to control, direct, and manipulate sound waves in ways not possible with conventional materials. Advanced materials achieve their properties through their structure rather than their chemical composition.
A property of certain gels or fluids that become less viscous when subjected to stress (such as sound waves) and return to their original state when the stress is removed. SoundBounce uses thixotropic properties to absorb acoustic energy.
An engineering term used to describe the study and modification of noise and vibration characteristics of vehicles. NVH engineering aims to reduce unwanted sounds and vibrations to improve comfort and quality.
Sound waves with frequencies typically below 250 Hz. Low-frequency noise is particularly difficult to control with traditional materials and can cause health issues including fatigue, headaches, and concentration problems.
A logarithmic unit used to measure sound intensity. A 10 dB increase represents a tenfold increase in sound intensity. Normal conversation is around 60 dB, while a rock concert can exceed 110 dB.
A measure of how much sound energy is absorbed by a material, ranging from 0 (total reflection) to 1 (total absorption). Different materials have different absorption coefficients at various frequencies.
The transmission of sound between rooms via indirect paths such as structural elements, ductwork, or gaps around doors and windows, rather than directly through the separating wall or floor.
A principle stating that doubling the mass of a barrier increases its sound transmission loss by approximately 6 dB. SoundBounce technology exceeds mass law predictions through advanced material engineering.
A phenomenon where sound waves hitting a panel at certain angles and frequencies cause the panel to vibrate in a way that reduces its sound insulation effectiveness.
A single-number rating used to measure how well a floor/ceiling assembly reduces impact sound transmission, such as footsteps. Higher IIC ratings indicate better impact sound insulation.
