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 loudness, or intensity, of sound is measured in decibels. For each increase of 10 decibels, the sound wave has 10 times as much energy. For example, a sound of 20 decibels is twice as loud as one of 10 decibels, but has 10 times the energy. The softest sound humans can hear, ...
While the pitch or frequency of the sound is measured in hertz or Hz, the higher the hertz the higher the pitch of the sound and vice versa (Hildebrand, 2004). 876 Words 4 Pages Decent Essays Read More Examples Of Vaulting Ambition In Macbeth In William Shakespeare's "Macbeth", the ...
It can cause hearing loss, _3_, high blood pressure, sleep loss, distraction, and lost productivity.Sounds are produced by objects that vibrate(振动) _4_ a rate that the ear can detect.This rate is called _5_ and is measured in hertz, or vibrations per second. Most humans can hear ...
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...

It is measured in hertz. The pitch of sound depends on the frequency of vibration. Quiz: Sound Sound is produced not only by vibrations in strings but also by vibrations in stretched skins or membranes, as well as by vibrations in air columns. In a tabla or drum, sound is produced when...
The frequency of a sound is the number of waves that pass a given point each second. [29] The more rapid, an object vibrates, the greater the frequency of sound it makes. Frequency is measured in hertz. One hertz equals one sound wave per second. The frequency of sound determines the...
The amplitude defines how loud the sound is and is usually measured in decibels (dB). 振幅定义了声音的大小,单位dB(杜比)。 The frequency is how many different wave oscillations fit into one second, measured in hertz (Hz). 频率是一秒内有多少不同的波振动周期,单位HZ(赫兹)。
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...
