What is a Standing Wave? A standing wave, also known as a stationary wave, is a pattern of oscillation that occurs when two waves of the same frequency and amplitude traveling in opposite directions interfere with each other. This interference creates a wave pattern that appears to be stationary, with points of maximum and minimum … Read more
What is Direct Sound? Direct sound refers to the sound that travels directly from the sound source to the listener without any reflections or interference from the surrounding environment. It is the purest form of sound that reaches our ears and is crucial for clear communication and accurate perception of audio signals. How is Direct … Read more
What is Ultrasonic? Ultrasonic refers to sound waves that are above the frequency range of human hearing, typically above 20,000 Hz. These high-frequency sound waves are used in various applications, including medical imaging, industrial cleaning, and pest control. Ultrasonic technology utilizes these sound waves to perform tasks that are not possible with audible sound waves. … Read more
What is Fundamental Frequency? Fundamental frequency, also known as the first harmonic, is the lowest frequency produced by a vibrating object. It is the building block of all other frequencies produced by the object and determines the perceived pitch of the sound. In simpler terms, it is the frequency at which an object naturally vibrates … Read more
What is Beat Frequency? Beat frequency refers to the difference in frequency between two sound waves that are slightly out of tune with each other. When two sound waves with slightly different frequencies are played simultaneously, they interfere with each other, creating a fluctuation in loudness known as a beat. This beat frequency is perceived … Read more
What is Sound Velocity? Sound velocity, also known as the speed of sound, refers to the speed at which sound waves travel through a medium. It is typically measured in meters per second (m/s) and varies depending on the properties of the medium through which the sound is traveling. In general, sound velocity is faster … Read more
What is a Longitudinal Wave? A longitudinal wave is a type of wave in which the particles of the medium vibrate parallel to the direction of the wave’s propagation. This means that the displacement of the particles is in the same direction as the wave itself. Longitudinal waves are commonly seen in fluids and gases, … Read more
What is Acoustic Holography? Acoustic holography is a technique used to visualize and analyze sound fields in three-dimensional space. It is based on the principles of holography, a method that captures the interference pattern of light waves to create a three-dimensional image. In the case of acoustic holography, the interference pattern of sound waves is … Read more
What is an Acoustic Marker? An acoustic marker is a specific sound or signal within an audio recording that serves as a reference point for various purposes. These markers are typically used in audio production to aid in the editing, mixing, and mastering processes. Acoustic markers can range from simple beeps or tones to more … Read more
I. What is Absorption Coefficient? The absorption coefficient is a measure of how well a material absorbs sound waves. It is a dimensionless quantity that indicates the fraction of sound energy that is absorbed by a material when sound waves pass through it. The absorption coefficient is typically represented by the symbol α and is … Read more
