Could be several different reasons. Are you using the same weight pellet. Different pellets create a slightly different sound. Also a new rifle has a break-in period, it takes about 100 to 200 shots for an air rifle to break in. The air chamber settles down over time. Or it could be just where you are standing. If you are close to a wall the sound bounces off the wall back to you. Also never dry-fire a pellet rifle this will damage the air cylinder and never leave an air rifle cocked for days on end, it will damage the spring.
100 times louder. You will hardly hear a 20 db(SPL) sound at all.
A 60 decibel sound is 10 times louder than a 40 decibel sound. Decibels follow a logarithmic scale, where an increase of 10 decibels represents a sound that is perceived as being 10 times more intense.
This statement is not accurate. The decibel (dB) scale is logarithmic, not linear. An increase of 10 dB represents a tenfold increase in sound intensity. So, a sound of 20 dB intensity is actually 10 times louder than one of 10 dB, not twice as loud.
The intensity of a 40 decibel sound is 100 times greater than that of a 20 decibel sound because every increase of 10 decibels represents a 10-fold increase in intensity.
1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.
Do you mean "What sound does a rifle make"? If you do, it makes a very loud "pop" similar to shooting a cap gun but about 1o times louder.
A sound wave with an intensity of 83 dB is about 8 times louder than a sound wave with an intensity of 70 dB. This is because the decibel scale is logarithmic, and every increase of 10 dB represents a sound wave that is 10 times more intense.
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.
30dB is louder than 21dB. The decibel scale is logarithmic, so each increase of 10 dB represents a tenfold increase in sound intensity. Therefore, 30dB is 10 times louder than 20dB.
A sound wave with an intensity of 50 dB is 1,000 times louder than a sound wave with an intensity of 20 dB. This is because every increase of 10 dB represents a 10-fold increase in intensity.
The power or intensity of the louder one is 10 billion times the power or intensity of the softer one. Since the power or intensity is typically proportional to the square of the wave amplitude, the amplitude of the louder one is a mere 100,000 times the amplitude of the softer one.
A 70dB sound is 10 times more intense than a 60dB sound. In terms of perception, the 70dB sound will be perceived as noticeably louder than the 60dB sound.
