How Loud is 20 dB Above Audibility?

In summary, when listening to music at a sound-level of 20 dB above the threshold of audibility, it would be considered very soft, as it is only 4 times as loud as barely audible. However, the qualitative response of the sound being slightly loud or of normal listening level is subjective and can vary depending on personal perception. The lowest level of sound that humans can hear is around 65dB.

On a day when you are listening to music at a sound-level of 20 dB above the threshold of audibility, an average person would say that it was
none of these
very loud
slightly loud
of normal listening level
very soft

Well, for every 10dB increase we percieve sound as twice as loud right? So would that make this slightly loud? its only 4 times as loud as barely audible, or would that be considered normal listening level? I'm just not sure what to classify the sound as.

You have the math right, but the qualitative response is just a bit arbitrary if you ask me >.<

yeah that's what i don't like about this question.

whats the lowest humans can hear, about 65db?
 

FAQ: How Loud is 20 dB Above Audibility?

1. What is sound measure?

Sound measure is a way to quantify the physical properties of sound waves, such as amplitude, frequency, and intensity. It is used to describe and compare different sounds, and is an important tool in fields such as acoustics, music, and communication.

2. How is sound measured?

Sound is measured using a unit called decibels (dB), which is a logarithmic scale that represents the loudness or intensity of a sound wave. A decibel meter is used to measure the sound pressure level (SPL) in a specific location, and the results can be compared to established standards to determine the level of noise pollution.

3. What is the difference between sound intensity and sound pressure?

Sound intensity is the amount of sound energy that passes through a unit area, while sound pressure is the amount of force that a sound wave exerts on a surface. In other words, sound intensity is a measure of the strength or power of a sound, while sound pressure is a measure of its physical impact.

4. How does frequency affect sound measure?

Frequency is the number of sound waves that pass through a point in one second, and it is measured in Hertz (Hz). As the frequency of a sound increases, the pitch of the sound also increases. Therefore, frequency is an important factor in sound measure, as it can affect how we perceive and understand different sounds.

5. Can sound measure be used to measure the quality of sound?

Yes, sound measure can be used to assess the quality of sound. The frequency, amplitude, and other properties of a sound wave can affect its perceived quality, such as whether it is clear, muffled, or distorted. By measuring these properties, we can determine the overall quality of a sound and make adjustments as needed.
