Acoustics_Vocabulary

Acoustics: is the term for the study of sound and how sound is experienced.

Flutter echo: Occurs when noise bounces between parallel surfaces in a room.

Noise: Unwanted sound. Noise can often be the individual perception of a particular sound.

Privacy: Acoustic privacy between working places in open plan offices is expressed with the Articulation Class.

Reverbation Time: The time it takes for the sound pressure level to fall by 60 dB after the sound has been turned off. Measuring the reverberation time allows us to calculate the total sound absorption. The reverberation time varies according to the frequency.

Sound absorbers: Materials and structures with the ability to take up sound energy and convert it into other forms of energy. They improve room acoustics by removing sound reflections, thus reducing the noise and the reverberation time.

Speech intelligibility: Speech intelligibility is directly dependent on the level of background noise, reverberation time and the shape of the room.

Soundproofing (Sound Blocking): If the objective is to stop sound from entering or leaving a space, then you will most likely need sound blocking or soundproofing. For example; your neighbor plays loud music at all hours of the day and night. The sound travels from their space into yours.

Sound Absorption (Acoustic Enhancement): If the objective is to enhance the properties of sound by improving speech clarity and sound quality, then the answer is sound absorption or acoustic enhancement. For example, your staff or students have difficulty clearly hearing in the conference room or auditorium during presentations.
