What is an Echo? An echo is a reflection of sound that arrives at the listener’s ears after the original sound has ceased. It is a repetition or imitation of a sound caused by the reflection of sound waves off a surface. Echoes can occur naturally in environments with hard surfaces that reflect sound waves, … Read more
What is Sound Absorption? Sound absorption refers to the process of reducing the reflection of sound waves. When sound waves hit a surface, they can either be reflected, transmitted, or absorbed. Sound absorption aims to minimize the reflection of sound waves, thereby reducing echo and reverberation in a space. This is particularly important in environments … Read more
What is Diffraction? Diffraction is a phenomenon that occurs when waves encounter an obstacle or aperture and bend around it, spreading out in all directions. This bending of waves is a result of interference between the waves as they pass through the obstacle or aperture. Diffraction can occur with various types of waves, including light … Read more
What is Acoustic Scattering? Acoustic scattering refers to the phenomenon where sound waves are reflected, refracted, or diffracted when they encounter an object or surface. This results in the sound waves being scattered in different directions, leading to changes in the intensity and direction of the sound. Acoustic scattering plays a crucial role in various … Read more
What is Bark Scale? The Bark Scale is a psychoacoustic frequency scale that is based on the perception of sound by the human ear. It was developed by Eberhard Zwicker and his colleagues in the 1960s and is named after Heinrich Barkhausen, a physicist who studied the perception of sound. The Bark Scale divides the … Read more
What are acoustic metamaterials? Acoustic metamaterials are a class of materials engineered to control and manipulate sound waves in ways that are not possible with conventional materials. These materials are designed with specific structures and properties that allow them to bend, reflect, or absorb sound waves in unique and controlled ways. By manipulating the propagation … Read more
What is Absorption? Absorption refers to the process by which sound waves are absorbed by materials rather than being reflected or transmitted. When sound waves hit a surface, some of the energy is absorbed by the material, converting it into heat. This reduces the amount of sound that is reflected back into the room, resulting … Read more
What is Sound Mapping? Sound mapping is the process of visually representing soundscapes or audio environments. It involves capturing and analyzing various aspects of sound, such as frequency, amplitude, and spatial location, and translating this data into a visual format. Sound mapping can be used to create detailed representations of acoustic spaces, allowing for a … Read more
What is White Noise? White noise is a type of sound signal that is characterized by a flat frequency response across the entire audible spectrum. It is called “white” noise because it is analogous to white light, which contains all the colors of the visible spectrum in equal amounts. In the case of white noise, … Read more
What is Audio Frequency? Audio frequency refers to the range of sound waves that can be heard by the human ear. These sound waves are measured in cycles per second, or hertz (Hz). The audible frequency range for humans typically falls between 20 Hz and 20,000 Hz, although this range can vary slightly depending on … Read more
