The purpose of acoustically conditioning a certain room (closed or outdoors) is to ensure that the sound from a source or sources is radiated equally in all directions, achieving an ideal diffuse sound field. The objective of the conditioning of a room is to achieve a degree of uniform acoustic diffusion at all points of the same. This is intended to improve the acoustic conditions of sound by increasing the internal acoustic comfort of the premises. It was first undertaken by Professor W. C. The function of acoustic insulating materials is to reflect most of the energy they receive. They must be heavy, flexible and continuous materials to get the most out of their weight. They are used to attenuate the passage of noise between different environments on floors, walls and ceilings. Wood acoustic ceilings and panels: how does sound absorption work? Acoustic panels made of sound-absorbing wood are the undisputed protagonists of any conditioning work. An acoustic diffuser is an element that, through the uniformity of the acoustic energy, will provide a more or less considerable improvement in the sound quality of an enclosure, spreading the acoustic energy incident on its surface in space and time.

The acoustic absorber is a type of materials used in the acoustic conditioning of rooms, due to its ability to absorb most of the sound wave they receive. Absorbent materials. The various materials in common use used as acoustic absorbers can be divided into: - Porous materials: they dissipate acoustic energy transforming it into heat. The most widespread porous material in 2005 was acoustic foam. Panel or membrane-shaped absorbers absorb low frequencies (bass) more effectively than high frequencies. Helmholtz absorber It is a type of artificially created absorber that specifically eliminates certain frequencies. Acoustic absorption. When a sound wave hits one of the surfaces in a room, part of the sound energy is reflected and part penetrates the surface. Part of the energy in the sound wave is absorbed into heat energy in the material, and the rest is transmitted around it. Reflection of sound. It is the bouncing of a sound wave off a hard surface. The sound that reaches the obstacle is called incident sound and the sound that is returned is the reflected sound. When a sound is reflected, it generally changes the direction in which it is propagated and loses a quantity of energy.
