Acoustic conditioning. Why is it important?
We have all been in a restaurant, school, hospital, canteen... and have had the feeling of listening to other people's conversations at a higher level than our own and have had to speak louder to be able to understand each other. This effect is due to a high reverberation in the room that makes the sound stay in the air longer than recommended, creating a sensation of constant noise.
We have just seen that, although in the first instance we may think that we should only worry about the acoustics of rooms intended for music and/or voice such as theatres, recording studios, concert halls... there are many other spaces where acoustics play an important role. In addition, many studies conclude that acoustically comfortable spaces contribute to increasing production and reducing pathologies related to noise excesses such as exhaustion, stress and voice problems or attention deficit among others.
What affects acoustic comfort in a space?
The fundamental parameter to be controlled when conditioning a space is the reverberation time, which is the time it takes for a sound source to decrease its intensity by one millionth. This means that spaces with high reverberation times the sound remains floating in the air longer than recommended creating a sensation of noise and bustle. Other parameters that must be controlled are:
- RT: The greater the reflection and the larger the space, the longer it takes for sounds to be absorbed. This leads to an increase in the reverberation time.
- Auditory masking: When the ear is exposed to two or more pure tones of different times, there is the possibility that one of them masks the others and, therefore, avoids their perception partially or totally. Likewise, it is easy to see the difficulty of understanding a conversation in the presence of noise.
- Intelligibility: the comprehension of speech depends fundamentally on the correct perception of its consonants, on the existence of echo or floating echoes in a room.
How to achieve an acoustically comfortable space?
To solve the problem of excessive noise in the enclosure, elements that can provide a high level of acoustic absorption that can absorb sound and reduce reverberation are needed, such as the acoustic absorption panels that we use at iTEKNA. Thanks to their properties and their wide range of shapes, colours and installation methods, manage to create a suitable climate of comfort within the spaces, thus enabling the activity of the enclosure to be carried out normally without noise problems. We explain everything about our acoustic absorption panels in this article.
