The Decibel (dB) Scale is a logarithmic unit used to measure the intensity of sound, among other things. It quantifies sound levels, making it an essential tool in acoustics, telecommunications, and various scientific fields.

A sound source is any object or device that generates vibrations, producing acoustic waves or sound. Understanding sound sources is essential in the study of acoustics and sound engineering.

Soundproofing materials are specially designed substances used to reduce or block the transmission of sound between spaces. They play a vital role in creating quieter and more peaceful environments.

Acoustic absorption is the process of reducing sound reflection within a space by using materials designed to absorb sound waves. It plays a crucial role in improving room acoustics and reducing unwanted noise.

Sound Transmission Class (STC) is a rating system that quantifies how effectively a building partition, such as a wall or door, reduces the transmission of airborne sound. Understanding STC is essential for designing acoustically efficient spaces.

Reverberation time is the duration it takes for sound to decay by 60 decibels in a closed environment, such as a room. It plays a critical role in room acoustics, impacting sound quality in spaces like concert halls and auditoriums.

Sound insulation is the process of reducing the transmission of sound from one area to another, providing a quieter and more comfortable environment. It’s essential in buildings to maintain privacy and minimise noise disturbance.

Noise pollution is the presence of excessive or disruptive noise in the environment, causing adverse effects on human health and the ecosystem. It’s a growing concern in urban areas and industrial settings.

The frequency spectrum refers to the distribution of frequencies present in a signal or wave, such as sound or electromagnetic radiation. It plays a crucial role in fields like music, telecommunications, and radio astronomy.
