[??p·t?·m?m ri‚v?r·b??r?·sh?n ‚t?m] (acoustics) The reverberation time which is most desirable for a given room size and a given use, such as speech, chamber music, or symphony orchestra. How do you calculate optimum reverberation time? The optimum reverberation time depends … Continue reading →

Noise is unwanted sound considered unpleasant, loud or disruptive to hearing.Acoustic noise is any sound in the acoustic domain, either deliberate (e.g., music or speech) or unintended. What is an undesirable loud sound known as? Unwanted or unpleasant sounds are … Continue reading →

An echo is a sound that is repeated because the sound waves are reflected back. Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. Although the direction of the … Continue reading →

Compression- a region in a longitudinal (sound) wave where the particles are closest together. • Rarefaction- a region in a longitudinal (sound) wave where the particles are furthest apart. What is a example of compression wave? Slinky Example Longitudinal waves, … Continue reading →

Some whales and dolphins use echolocation to locate food. They send out pulsed sounds that are reflected back when they strike a target. The analysis of the echoes helps the animals determine the size and shape of an object, its … Continue reading →

Marine animals aren’t big on body language. Instead, they use sound to communicate. Some use sound to hunt, engaging echolocation to find and sometimes to stun their prey. Sound travels differently through water than it does through air, but water … Continue reading →

UHF radio waves. Bluetooth uses short-wavelength UHF radio waves of a frequency range between 2.4 and 2.485 GHz. Bluetooth enables one to create a personal area network wherein multiple devices talk to each other wirelessly via Bluetooth—a typical usage is … Continue reading →

Mono sound is when only one channel is used to convert a signal to a sound. Stereo sound is when multiple channels are used to convert multiple signals to sounds. What is better mono or stereo? Stereo isn’t necessarily better … Continue reading →

Drawbacks or disadvantages of Loudspeaker ?They are bulky in size compare to normal indoor speakers. ?They need large space. ?They are prone to interference from nearby radio equipments or other radio microphones. ?They consume large power due to its technical … Continue reading →

This return of noise is an example of echo. The sound reflects back to the listener as the frequencies bounce off hard objects such as ceilings and walls. The sound of a humming guitar string that continues after plucking is … Continue reading →

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.All waves can be thought of as a disturbance that transfers energy. What are the 4 … Continue reading →

Sound waves can not be seen and hence we can not pressure waves due to sound energy. Sound can not travel through the vacuum. The sound energy should be below a certain power level, otherwise, it can be annoying to … Continue reading →
