Never forget to tell the distance of the measuring microphone (at the place of your ear), from the the sound source because the closer you are to the sound source the louder it will be.
The sound pressure level decreases by 6 decibels per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.
The sound pressure decreases inversely as the distance increases with 1/r from the sound source.

Which is sound measured by watts meters amps or decibels?
Decibels
How many decibels is quiet conversation?
20 to 50 decibels (dB).
How does decibels work?
To calculate the number of decibels that power-level-'A' is greater than power-level-'B',-- Divide 'A' by 'B'-- Take the 'log' of the quotient-- Multiply the 'log' by 10 .If the result is negative, then 'A' is that many decibels lower than 'B'.
What is the normal decibel of a human voice?
The decibel level for standard human voices is around 60 decibels, which is also the level for singing birds. Hearing loss occurs at around 110 decibels with painful hearing loss occurring at 130 decibels.
How loud is 109 decibels?
109 decibles
How can sound damage us?
Very loud sounds, starting at about 125 decibels can cause ear pain or ear damage.
What decibels should ear defenders be worn?
Ear defenders should be worn in environments where the noise level exceeds 85 decibels to protect against hearing damage. It is important to select ear defenders with a Noise Reduction Rating (NRR) appropriate for the specific noise level in the environment.
Does voltage current or power affect volume in a speaker?
Power (Watts)/ Decibels (if the speaker is efficient) 2 Watts = 93 decibels 4 Watts = 96 decibels 8 Watts = 99 decibels 16 Watts = 102 decibels 32 Watts = 105 decibels 64 Watts = 108 decibels 128 Watts = 111 decibels 256 Watts = 114 decibels 512 Watts= 117 decibels 1024 Watts = 120 decibels Some Volumes to Compare 10 decibels = normal human breathing 60 decibels = normal human conversation 110 decibels = power saw, car horn, shouting in ear, 120 decibels = jet aircraft close by, emergency vehicle siren, rock concert
Is 92 decibels damaging to hearing?
Yes, prolonged exposure to 92 decibels can cause hearing damage. It is recommended not to be exposed to noise levels above 85 decibels for an extended period of time without ear protection to prevent hearing loss.
How does the human ear respond logarithm to intensity?
Intensity can be measured by converting units of electrical power in to decibels.
What is the decibel limit of human ear?
im an anonymus,but i read somewhere that about 80 decibels it's dangerous,abouve 100 decibels is painful,and 150 is the limit.not sure,Google it.answer from Romania :D
What is potentially harmful to the human ear?
Loud noise exposure, such as from firearms, loud music, or machinery, can be harmful to the human ear. Prolonged exposure to loud noises can lead to hearing loss or damage to the delicate structures in the ear. Additionally, inserting objects into the ear canal, like cotton swabs, can also damage the ear.
What noise level is120 decibels?
120 decibels is considered extremely loud and can cause immediate harm to hearing if exposure is prolonged. It is equivalent to the noise level of a chainsaw or a rock concert. It is important to use ear protection in environments where noise levels reach 120 decibels.
What is the smallest level of db the human ear can hear?
The human ear can detect sounds as low as 0 decibels, which represents the threshold of hearing. At this level, the sound is just barely audible to the average human ear in ideal conditions.
How loud do sounds have to be to damage the ear?
Sounds over 85 decibels, especially prolonged exposure, can cause damage to the ear. Exposure to sounds over 120 decibels, such as jet engines or gunshots, can cause immediate harm. It's important to protect your ears with earplugs or earmuffs in loud environments.
How many decibels does a jackhammer have?
A jackhammer typically produces sound levels of around 100-120 decibels. Prolonged exposure to noise at this level can lead to hearing damage, so it is important to wear ear protection when using or working near a jackhammer.
What is brief description of sound level?
Sound level is a measure of the intensity of sound, typically expressed in decibels (dB). It is used to quantify how loud a sound is perceived to be by the human ear. Different sound levels can have varying effects on human health and well-being.
