Why is dB IL equal to dB SPL?
IL is not equal to SPL. Actually SPL = IL + 0.16dB.
What is 100 kHz in DB?
You must tell us the reference frequency for 0 dB.
What decibel range can a human hear in?
We can hear from 0 dB, that is the threshold of hearing up to 130 dB that is the threshold of pain.
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.

How many milliwatts in 36 dB?
I guess the reference power for 0 dB is 1 milliwatt. Then the power level 36 dB means a power ratio of 10^(36/10) = 3981 to 1.
Why is dB IL equal to dB SPL?
IL is not equal to SPL. Actually SPL = IL + 0.16dB.
How do you converts ohms to dB?
You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.
Threshold of human in db?
The threshold of hearing is 0 dB. The threshold of pain = 137.5 dB.
What does sensation level mean?
The sensation level is measured in decibels. It is frequency specific and starts at 0 dB SL (sensation level) where 0 dB SL is the softest the patient can here a specific frequency. This means that the SL will be different for different people. Everyone's SL will start at 0 but my SL at 1000 Hz may be at 23 db IL and another's may be at 54 db IL.Put more simply, dB SL is the difference between a person's threshold of hearing and the presentation level of a stimulus. If a person's speech reception threshold (SRT) is 10 dB on an audiometer (dB HL) and you present a speech stimulus to them at 50 dB HL on the audiometer, their sensation level would be derived thus: 50 dB (presentation level) minus 10 dB (threshold), which equals a sensation level of 40 dB SL. This is also the procedure for a frequency-specific stimulus (e.g. pure tones): subtract the audiometric threshold (dB HL) from the supra-threshold presentation level (dB HL) and the difference is the sensation level (dB SL).
What is 100 kHz in DB?
You must tell us the reference frequency for 0 dB.
What is 45 percent in decibels?
100 percent is 0 dB.50 percent is - 6 dB.45 percent is -6.935749724 dB.10 percent is - 20 dB.
How loud is 69 db?
Since the db scale is relative, it depends on what 0 db means. Typically, however, 69 db is a very soft sound, almost a whisper.
Send me the conversion for Kilo HZ to DB?
Send me the reference value (0 dB) for frequency.
How much dB you can hear by your ears?
You can start to hear at the threshold of hearing at 0 dB and end up at the threshold of pain at 137.5 dB.
25dB equal to how many watts?
That depends on you. If you want, you can say 1 watt should be 0 dB.
What decibel range can a human hear in?
We can hear from 0 dB, that is the threshold of hearing up to 130 dB that is the threshold of pain.
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.
