What is Acoustics?

Acoustics is defined as the science that deals with the production, control, transmission, reception, and effects of sound. Many people mistakenly think that acoustics is strictly musical or architectural in nature. While acoustics does include the study of musical instruments and architectural spaces, it also covers a vast range of topics.

A scientist or researcher who studies acoustics is called Acoustician and someone working in the field of acoustics technology will be called as Acoustical Engineering. The main application of acoustics is to make the music or speech sound as good as possible. It is achieved by reducing the sound barriers and increasing the factors that help in proper transmission of sound waves. Initially, acoustics was used only in industries which are based on sound like an auditorium, theatre but today, the application of acoustics has spread to many fields like medicine, warfare, architectural industries, etc.


Environmental Acoustics

Environmental Acoustics is concerned with vibration and noise caused by roadways. Railways, aircraft and general activities that are related to the environment. The main goal of these is to reduce vibration and noise that affects the environment.

Musical Acoustics

Musical acoustics is concerned with the study of physics of music i.e., how sounds are used to make music. Areas of study include human voice, musical instruments, and music therapy.

Ultra Sound Acoustics

Ultrasounds are the sounds with a frequency greater than the human audible limit. However, there is no difference in physical properties when compared to normal sound. Ultrasound is used in many fields. Ultrasonic devices are used in measuring distances and in detecting objects. Ultrasound imaging is used in physics.

Infra Sound Acoustics

Infrasounds are the sounds with a frequency of less than 20 Hz. The study of such sounds is called infrasonics. Applications include detection of petrol formation under the earth and the possibility of earthquakes.

Vibration and Dynamics

It is the study of how mechanical systems vibrate and interact with their environment. Applications include Vibration control which helps to protect a building from earthquakes and ground vibrations used in railways.
