What is an example of a sound that is intense but not loud?

In summary, the conversation discusses the difference between intensity and loudness in sound waves and how a sound can be intense but not loud if it falls outside the human hearing range. An example given is a sound with a frequency of 20 kHz and an intensity of 120 dB SPL, which may not be heard by someone of a certain age but can still have a strong physical impact. Further insight is sought from an expert on the subject.

Really good question!

Intensity refers to a physical property of the sound wave (related to its amplitude), while loudness is the perceptual quality that is experienced.

My guess is that if a pure tone is of a frequency way outside of the human hearing range, it could have a very high amplitude and intensity, but still would not be heard. I'm not sure how far outside normal hearing range you would have to go because psychophysical researchers have found relationships between frequency and amplitude in determining perceived loudness ("equal loudness curves"). Maybe an expert will drop by and provide more insight.

i guess an example would be a very "intense" sound (like 120 dB SPL) at 20 kHz. someone my age is likely not to hear it, but it might strip the skin offa you.
 

FAQ: What is an example of a sound that is intense but not loud?

What is an example of a sound that is intense but not loud?

An example of a sound that is intense but not loud is the sound of a mosquito's wings buzzing. While the sound may be intense and noticeable, it is not considered loud in comparison to other sounds.

How can a sound be intense but not loud?

A sound can be intense but not loud if it has a high frequency or pitch. This means that the sound waves have a shorter wavelength and are perceived as more intense, but may not necessarily be loud in terms of decibels.

Can a sound be both intense and quiet?

Yes, a sound can be both intense and quiet. For example, the sound of a rustling leaf can be intense due to its frequency, but may not be loud in terms of decibels.

What factors contribute to a sound being intense but not loud?

Factors that contribute to a sound being intense but not loud include frequency, distance from the source of the sound, and the sensitivity of the listener's ears. Additionally, the environment in which the sound is heard can also affect its perceived intensity.

How is intensity different from loudness?

Intensity refers to the amount of energy or power in a sound wave, while loudness is a subjective perception of how loud a sound is to an individual. A sound can be intense in terms of its energy, but may not be perceived as loud by everyone. Loudness is also affected by factors such as age, hearing ability, and background noise.
