Acoustic Architecture Foto Commo

Acoustic architecture is the science that is responsible for studying acoustic control in closed spaces and buildings, either to achieve adequate sound insulation between different rooms or to improve acoustic conditioning inside internal spaces.

It has two branches: building acoustics and room acoustics.

The first studies the transmission of sound through walls, doors and floors. While the second focuses on how sound behaves within a room.

This science is gaining more and more importance. 50% of the population is regularly exposed to levels of noise that are harmful to health. This can cause discomfort and disorders that can affect people's quality of life. In addition, the World Health Organization (WHO) identifies environmental noise as the second most important risk to environmental health.

It must be taken into account that architecture has the responsibility of offering buildings that are practical and healthy for society and that take into account aspects such as sound health to guarantee the well-being of people and avoid noise pollution.

There is the “Noise Law”, which establishes the maximum noise and vibration values that can be produced by the building's own facilities, environmental noise from outside and from activities that take place in the same building and/or in adjoining premises.

The most effective solutions to reduce noise in buildings:

  • Noise insulating roofs: they are based on putting insulating material such as rock wool or polyurethane foam and waterproof material, adapting to the structure of both pitched and flat roofs.
  • Insulating facades: these can be a ventilated facade or a curtain wall.
  • Soundproof walls: these can be double wall or double ceramic sheet if the project is more complex.
  • Floating floor: it will help reduce the noise of footsteps, movement of furniture and other actions.
  • Acoustic insulation of ceilings and walls: it can be done on a false ceiling or under a slab by means of SOUND ABSORBING PANELS.

Taking these aspects into account, you can gain in health and quality of life and enjoy a peace of mind in our home that allows us to relax and rest

'Acoustics' in architecture relates to improving sound quality in interior spaces. Although it is a complex science, it is easy to explain, it contains 2 elements, the soundproofing that is equivalent to “less noise” and the treatment to “better sound”.

Sound treatments are used when you want to improve the sound quality in a space: for diners to hear each other in a restaurant, for students to understand their teachers, or for the whole audience to enjoy music in An auditorium.

Absorption (lower noise) is defined as incident sound hitting a material without being reflected. An open window is an excellent absorber, since sounds that pass through it are not reflected. The more fibrous a material is, the better the absorbency and denser materials are generally less absorbent. In general, low frequency sounds are very difficult to absorb, due to their long wavelengths. However, we are less sensitive to these types of sounds, so we generally don't need to treat a room to absorb these types of frequencies.

Diffusion is the method that allows the propagation of sound energy to improve the sound in a space. Diffusion spreads the reflected sound energy in a room, which also reduces the damaging effects of echo and reverberation. For example, a diffuser is a curved, fabric-covered panel that can be easily attached to walls and ceilings. These panels have the advantage of evenly spreading reflections from flat walls, which would otherwise combine with the original sound waves to create destructive interference. In a concert hall diffusion panels are used to enhance the richness of the sound and create a feeling of spaciousness.

The best-known unit of measurement is decibels (dB), a normal conversation is around 60 decibels, 10 dB is what normal breathing emits, 30 dB refers to a soft whisper and 50 dB generates a relaxing noise of rain, 85 dB is already equivalent to the noise of a congested street, 110 dB to a crying baby next to you and 120 dB to the intensity of thunder.
