Sound is measured in terms of frequency (Hertz), amplitude (decibels), and wavelength (meters). 9 Can sonic waves be harmful? High-intensity sonic waves can be harmful, causing damage to hearing or even physical harm at extreme levels. 9 How are sound and sonic related? Sonic is a subset...
Sound or acoustic energy was a form of energy which propagates through matter and is received by a being or device capable of interpreting it. Its intensity can be measured in decibels, while the pitch of sound is measured in hertz. (citation needed •
The frequency of a sound is measured in Hertz (Hz) and the infrasonic range is generally considered to be between 1 and 20 Hz. What sort of frequency spectrum is found in an infrasonic elephant call? Elephants make a variety of vocalizations including rumbles, screams, and trumpets. Rumble...

because it is easier to show that way.Audio SpectrumA low frequency of vibration has a low pitch and makes a deep sound, like a growl.A high frequency has a high pitch, like a whistle.Sound frequency is often measured in "Hertz" (Hz) which is how many vibrations per second.Example...
该句大意是“这一速率被称为频率,并以Hertz来测量”。由物理知识或后面的vibrations per second可知,Hertz是频率的单位。因此可知本题选B’ be measured in+测量单位的复数形式表示“以……来测量”。另外,由第四段中出现的measured in decibels也可判断出此处选B。 [词义分析] with“和,用”;in“以,按”;...
Rhythmic sound vibrations produce sound waves which travel in every direction. The frequency of a sound is the number of waves that pass a given point each second. [29] The more rapidly an object vibrates, the greater the frequency of sound it makes. Frequency is measured in hertz. One ...
Frequency:Thefrequency of soundrefers to the number of sound waves a sound produces per second. A low-frequency sound has fewer waves, while a high-frequency sound has more. Sound frequency is measured in hertz (HZ) and is not dependent upon the medium the sound is passing through. ...
One of the ways sound is measured is in periodic vibrations, which ishertz(or Hz), which is the property of sound that determines pitch. Humans have a finite range of frequencies they can hear, specifically, 20 to 20,000 Hz. Those frequencies are broken into octaves which are: ...
(A cycle can also be measured from any point on the curve to the next corresponding point.) The frequency of a sound is measured in cycles per second or hertz (abbreviated Hz). The amplitude is the greatest amount by which the concentration of air molecules varies from the normal. The ...
