SOUND
Sound
Sound is a physical phenomenon that is produced when an object vibrates. The vibration is transmitted in the form of sound waves and it must travel through a “medium” such as
air, water and wood. The speed of sound through air is 340 meters per second
(m/s). Sound cannot travel through a vacuum because there are
no particles to carry the vibrations.
Acoustics is the scientific study of sound. It also refers to the properties of a
room that
cause it to reflect, refract, and
absorb sound. It is important to
control how sound behaves to design spaces such as auditoriums, theaters and libraries. In an auditorium, acoustic design helps sound travel so that everyone can hear the music, while in a
library acoustic design prevents sound from traveling to keep the environment quiet.
It is essential to consider the reflection, absorption and transmission of sound. When a
wave reaches surfaces such as walls, floor and ceiling, part of the wave
is reflected, part is
absorbed and part is transmitted to the other side. There are materials that reverberate or absorb more
than others, e.g. tiled floor compared to carpeted one.
QUALITIES OF SOUND
Every sound has four qualities: intensity, pitch, duration and timbre.
