If you were to take two identical waves and line them up with each other, matching up the peaks and troughs, the two waves are said to be “in-phase,” which, when summed, results in an even larger wave (louder sound). But what happens if you delay one of the waves by exactly ...
If a sound intensity level of 0 dB at 1000 Hz corresponds to a maximum gauge pressure (sound amplitude) of 10^-9 atm, what is the maximum gauge pressure in a 60-dB sound? Briefly explain the frequency theory of hearing. What are the sounds of Korotkoff and how does each sou...
How does the speed of sound in air vary with temperature ? View Solution A source of sound and an observer are approaching each other with the same speed, which is equal to (110) times the speed of sound. The apparent relative change in frequency of source is View Solution Answer the...
When a wave is reflected, its speed An ocean wave usually occurs at a frequency of 0.2 hz. What is the period of each wave? How does increasing amplitude affect wavelength? Two electromagnetic waves are emitted from a source. Wave A has a wavelength of 383 nm while wave B has a wavelen...
When two identical waves are aligned at 0 degrees, they reinforce each other resulting in increased amplitude. When they are 180 degrees out of phase, they cancel out. Often times, sound waves are not perfectly in or out of phase, but rather somewhere in between. When this is the case, ...
First, it has multiple microphones, so it's able to pick up different sound wave structures on each mic. Because the mics are arrayed around the device, each mic will pick up a given sound event at a very slightly different time, and with a very slightly different wave. If, and ...
Ultrasonic: It is a sound with a frequency more than 20,000Hz. What are the 4 properties of sound? Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are thefrequency, amplitude,...
Increasing the amplitude means that there is a larger distance to travel, but the restoring force also increases, which proportionally increases the acceleration. This means the mass can travel a greater distance at a greater speed. These attributes cancel each other, soamplitude has no effect on...
transmitted in electric pulses of varying amplitude, while digital sound transmits the signal in a series of 1s and 0s. This required new playback devices, and a new crucial component: the digital-audio converter, which transforms the digital signal into an analog wave so we can still hear ...
(receiver). This particular wave is defined by a frequency where the amplitude & the phase are modified to indicate unique bits of information to the target. So, Stronger the frequency, the better the connectivity, but just like sound, there is only so much we can do to increase the ...
