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 •
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”;...
The most common unit of measurement for sound is decibels (dB), which measures the intensity or loudness of the sound. The frequency of sound is measured in hertz (Hz), with a higher frequency indicating a higher pitch. Sound can also be measured in terms of its wavelength, usually in me...
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 ...
This rate is called frequency and is measured in hertz (赫兹), or vibrations per second. Most humans can hear sounds between 20 and 20,000 hertz, while dogs can hear high pitched sounds (高频声音) up to 50,000 hertz. While high frequency sounds tend to be more hazardous (危险的) and...
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...

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: ...
