Soundproofing Technologies And Techniques
What is Soundproofing?
Soundproofing is the process of developing acoustic treatments to suppress, reflect, diffuse or absorb sound waves either at the source using products such as baffling or insulation on automotive engines, pipes/ducting or machinery rooms, or at the destination using technologies such as double glazed windows and insulation to reduce unwanted external noise from road traffic, airports and other rooms within offices, apartments and other residential dwellings.
A range of techniques can be used to reduce sound within a room:
Porous or resonant absorbing materials can be installed to convert sound wave energy into a tiny amount of heat effectively reducing the amount of sound that is reflected around a room. Soundblock Solutions use Plano Bevel Tiles for sound absorption within restaurants, hotels, schools, home theatres and many other commercial and residential applications. Soundblock Solutions carry a range of sound absorbing products including: Echohush Profile Panels, Sonex Acoustic Foam, Quietstone Light and Reapor Soundproofing.
Irregular surfaces can be used to break down, or scatter sound waves so that they travel along many smaller paths. This results in the overall energy of the sound wave depleting faster and therefore travelling less distance.
Reflecting sound waves is a common technique for reducing traffic noise on freeways and other major traffic routes. Typically hard surfaces such as concrete or glass are used to bounce sound waves upwards (into the sky) or away from buildings. The overall architecture of a building including material and angles can also be used to effectively reflect sound.
Soundproofing falls into two main categories as follows:
Reducing sound within a room
Soundproof rooms, also known as anechoic (echo free) or semi-anechoic chambers, are designed to reduce unwanted reverberation and echo within a room for the purposes of sound-quality (e.g. recording studios and home theatres) or noise mitigation e.g. hotels, bars, restaurants, and open-plan offices. Room soundproofing typically also includes insulation to reduce unwanted external noise.
Limiting sound leakage
Soundproofing materials can be utilised to limit the transference of sound waves between rooms (either adjacent, above or below) and from external sources. A range of items within a room or rooms can be soundproofed including windows (double glazing), floors, walls, ceilings and doors. Existing or traditional windows can be fitted with an acoustic secondary windows using one of our two retrofitted Soundblock solutions; Soundout Aluminium Window or Soundblock Acrylic Magnetic Window.
