Better think of the sound pressure, when you are listening. Sound pressure moves your ears and the diaphragm of the microphones. The sound intensity is very small. The level of 50 dB is equal to 0.0000001 W/m2 acoustic intensity. Scroll down to related links and look at "Conversion of sound units (levels)".

What is louder 30dB or 21dB?

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 of 20 dB intensity is twice as loud as one of 10dB?

No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10.

What is the intensity of 20db sound?

The intensity of a 20 dB sound is approximately 10^-8 watts per square meter. Sound intensity is measured on a logarithmic scale, where each 10 dB increase represents a tenfold increase in intensity.


How much louder is 50db then 30db?

The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity


What is the maximum and minimum intensity of sound that human call can ear?

The human ear can typically detect sound intensities ranging from about 0 dB (threshold of hearing) to 120-130 dB (threshold of pain). Sounds below the threshold of hearing are too faint for the ear to detect, while sounds above the threshold of pain can be physically uncomfortable or damaging to the hearing.

What is the significance of the -20db level in audio engineering and how does it affect sound quality?

The -20dB level in audio engineering is significant because it represents a common reference point for setting audio levels. It is often used as a standard level for recording and mixing audio to ensure consistency and prevent distortion. Maintaining audio levels around -20dB helps to optimize sound quality by providing a good balance between signal strength and background noise, resulting in clear and natural-sounding audio recordings.


What must you do to the strings on an instrument to make a louder sound?

Amplifying, or amplification would be common descriptors for the process of making sound louder.In musical instruments, sounding boards are one common practice. These vibrate a larger surface. This applies to piano and violas. A horn or trumpet is a device for matching the impedance of the source to that of free air, and this device is used in the brass instruments(including the digeridoo!) and some wood wind instruments. A car horn and a speaking trumpet are other examples.These simple systems may give in excess of 20dB amplification. (100 times).


What is PAD in Audio application?

It is either:- Pad button, that is found on some preamps and it is used for lowering input gain, usually by -20dB.- Synth pad, that is a a sound used in electronic music which is a harmonic background sound


How many decibels in the average whisper?

Between 1 and 20db


What is the meaning of 20dB per decade?

I assume you are looking at bode plots. 20dB per decade means an increase or decrease in signal strength of 20dB for every decade of frequency (10Hz to 100Hz is a decade, 100 Hz to 1000Hz is a decade). This is common talk when discussing filters. If you want further (graphical) explanation, search wikipedia for "bode"
