What is normal loudness?

Loudness is usually described in decibels, which is a logarithmic scale based on sound pressure level. If the threshold of hearing (for healthy ears) is taken as 2 x 10-5 Pascals, and this is called 0 db, then a fairly normal level such as you would find in a room in a house with the TV on is a sound pressure level 1000 times greater, ie 2 x 10-2 Pascals, and on the db scale this will be 60 db. Recommended maximum level for working is usually 90 db, above this ear defenders should be used. See the Wikipedia article on 'Decibel' (1 Pascal is 1 Newton per sq meter)

What is associated with the loudness of sound waves?

Loudness is affected by parameters other than sound pressure, including frequency and duration. In acoustics volume is related to amplitude, sound pressure, and dynamics.The loudness of a sound can be measured by a sound pressure level meter. It belongs to psycho acoustics.Loudness is a subjective measure, which is often confused with objective measures of sound prtessure such as decibels or sound intensity. Filters such as A-weighting attempt to adjust sound measurements to correspond to loudness as perceived by the average human. However, as the perception of loudness varies from person to person it cannot be universally measured using any single metric.There is subjectivly perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).Scroll down to related links and look at "All about loudness".


Determined by the amount of energy a sound wave carries?

A radio going in the background will be radiating a few tens of milliWatts of sound from its speakers. [Loudspeakers are rather inefficient, particularly so for high quality ones. 10% would be a good figure, - perhaps 3% for a high quality one.] So a say 60 Watt (RMS) amplifier and appropriate speakers; which would sound really loud; would be radiating a few watts of sound.

What does 10 decibels sound like?

A quiet conversation is about 60 decibels. The sound of rustling leaves is about 40 decibels. The sound of a mosquito at 3 meters is said to be about 1 decibel.


Which is louder 60 or 70 decibels?

40 dB gain change should give about the ratio of 16 for sensed volume and loudness, 40 dB gain change gives the ratio of 100 for measured voltage and sound pressure and 40 dB gain change gives the ratio of 1000 for calculated sound power and acoustic intensity. Go to the link: Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).


How many decibels are produced by a normal conversation?

That depends how close you measure to the mouth speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. A conversation in 1 meter distance may have 60 decibels.


What does 60 decibels sound like?

Go through the chart at the link below. Scan the whole chart; some levels are described more than once. Normal conversation is about 60 decibels, and ordinary piano practice is between 60 and 70 decibels.


80 decibels is how many times louder than 60 decibels?

The sound pressure level of 80 dB is a 10 times higher measure than the sound pressure level of 60 dB. Louder ist not the correct word, because it belongs to psycho acoustics and tells the loudness feeling.


How many decibels is a normal conversion?

That depends how close you measure to the speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. In 1 meter distance the sound pressure level is arround 60 decibels SPL.


What is the loudness of sound of the normal conversation?

The sound of a normal conversation is 60dB (decibels) and a close range jet is 140dB. This makes a jet at close range over 2 times as many decibels than a close range jet. The sound of a normal conversation is 60dB (decibels) and a close range jet is 140dB. This makes a jet at close range over 2 times as many decibels than a normal conversation. The above answer is FALSE: The decibel scale is logarithmic and thus a 140 dB sound would be 10^14 above 0 decibel; the 60 dB sound would be 10^6 above 0 decibel. Thus the close range jet is around 10^(14 - 6) = 10^8, or 100,000,000 times the loudness of a normal conversation.

How loud is 60 65 70 decibels in relations to everyday sounds?

The range of 60-70 decibels sound pressure level is about as loud as normal conversation in 1 meter distance. The distance from the ears to the sound source is very important to the value of the SPL. Scroll down to related links and look at "Table of Sound Pressure Levels".
