How do you calculate sound pressure level of a fire alarm horn?
Use a sound pressure level meter. But don't forget to mention the distance when you write down the value in decibels. The more far away you are from the horn the lower is the measured level. A dB value without the distance is useless. For example, the UL standard for smoke alarms is 85 dB at 10 feet.
How much greater is the sound pressure level of a 100 dB siren than an 80 dB alarm clock How much louder would most people perceive the siren to be?
The sound pressure level of a 100 dB siren is 100 times greater than that of an 80 dB alarm clock. Most people would perceive the 100 dB siren to be around twice as loud compared to the 80 dB alarm clock due to the logarithmic nature of the decibel scale and human perception of sound intensity.
What is db in binary?

How do you convert amps to dB?
You don't. They measure quite different things, so there is no standard conversion. Ampere is a unit of electrical current. Decibel (dB) is a measure of signal gain.
What does NRR equals 30 db mean?
NRR means Noise Reduction Ratio and 30 db (decibels) is about average. 30db hearing protection would be commonly used by shooters to reduce the sound of gun fire.

How do you convert from db HL to db SPL?
To convert from dB HL (Hearing Level) to dB SPL (Sound Pressure Level), you typically need the specific audiogram for the individual. Once you have the individual's threshold values at different frequencies, you can use them to make the conversion. Each audiometric frequency has a specific conversion factor to convert from dB HL to dB SPL. It is not a direct and consistent conversion across all frequencies.
What color is lighter db 701 or db 703?
