Shock absorbing techniques

We define the process of diminishing the amplitude of vibrations as shock-absorption.  All of the components of the Artesania-audio products (structures, treatments, shelves, cushions, discs etc.) are designed to increase the absorption coefficients to dampen the negative effects that resonance can cause throughout the whole of a sound system.  The achieved effect of this design is to reduce (up to 80 to 90% according to the rack) the lowest frequencies (of highest width and wavelength) and transform their point of resonance to that of higher frequencies, (of a lower width and wavelength) as these do not affect the sonic performance.

Resonance

This is the phenomenon by which an object vibrates at its natural frequency while being influenced by another body vibrating at the same frequency. This can cause harmful effects.

The “Larsen Effect”

This is more commonly known as positive audio feedback and produces a distorted, closed sound loop at low frequencies in both analogical and digital sound sources. It results in distorted sound in speakers, (especially floor speakers) further distortion from transmission through solid matter (walls, racks etc.) and, in particular, negative effects from sound transmission through the floor; these can vary in velocity according to the type of floor material and treatment within the sound area.

It is a special type of low frequency feedback, which results from the creation a loop between an audio input and an audio output (a microphone and speaker for example.) The repeated reintroduction of sound from the microphone is transmitted from the speaker, causing distortions in the low frequencies.

The “Jitter” effect

This is technically defined as a “temporary fluctuation in the synchronisation of the electronic circuits.”

Interference

This is produced when acoustic waves of the same frequency travel in the same direction and combine to either reinforce or cancel each other out.
