Audio Terms Glossary

What is Acoustic Beamforming? Acoustic beamforming is a signal processing technique used in audio engineering to enhance the directional sensitivity of microphones or loudspeakers. By combining signals from multiple transducers, such as microphones or speakers, acoustic beamforming can focus sound waves in a specific direction while suppressing noise and interference from other directions. This technology … Read more

What is a Standing Wave Pattern? A standing wave pattern, also known as a stationary wave, is a wave that appears to be stationary in space. It is formed by the interference of two waves traveling in opposite directions with the same frequency and amplitude. The result is a pattern of nodes and antinodes that … Read more

What is Sound Sampling? Sound sampling is the process of capturing and recording a snippet or segment of a sound or piece of music for reuse in a new composition. This technique involves taking a small portion of a sound recording and manipulating it to create a new sound or piece of music. Sound sampling … Read more

What is a Soundproof Enclosure? A soundproof enclosure is a structure designed to reduce or eliminate the transmission of sound from one area to another. It is typically used to contain noisy equipment or activities within a confined space, preventing the sound from disturbing people in the surrounding area. Soundproof enclosures are commonly used in … Read more

What is Sone? Sone is a unit of loudness measurement that is used in the field of audio engineering. It is a subjective unit that is based on the perception of loudness by the human ear. Sone is used to quantify how loud a sound is perceived to be by an average listener. The Sone … Read more

What is Room Criteria (RC)? Room Criteria (RC) is a measurement used to evaluate the acoustic quality of a room. It is a standardized method of quantifying the sound absorption, reflection, and reverberation characteristics of a space. RC values are used to determine how well a room will perform acoustically, particularly in terms of speech … Read more

What is an Audio Signal? An audio signal is a representation of sound in an electrical form. It is a waveform that carries information about the sound it represents. Audio signals are used in various applications such as music production, telecommunications, broadcasting, and speech recognition. How is an Audio Signal Produced? Audio signals are produced … Read more

What is an Acoustic Pulse? An acoustic pulse is a short burst of sound waves that propagate through a medium, such as air or water. These pulses are characterized by their high intensity and short duration, typically lasting only a few milliseconds. Acoustic pulses are used in various applications, including medical imaging, underwater communication, and … Read more

What is Acoustic Pressure Level? Acoustic Pressure Level refers to the measurement of the pressure variations in a sound wave. It is a crucial parameter in the field of acoustics as it determines the intensity of sound and its impact on the human ear. Acoustic Pressure Level is often expressed in decibels (dB) and is … Read more

What is Acoustic Monitoring? Acoustic monitoring is a method of collecting and analyzing sound data in various environments using specialized equipment. This technology allows researchers to track and study acoustic signals produced by animals, machinery, or natural phenomena. By capturing and analyzing sound waves, acoustic monitoring provides valuable insights into the behavior, health, and interactions … Read more
