Send me the reference value (0 dB) for frequency.
You cannot directly convert hertz (Hz) to decibels (dB) because they measure different quantities. Hz measures frequency, while dB measures the level or intensity of a sound signal. To get dB from Hz, you would need to measure the intensity or power of the sound and then calculate the corresponding dB value using a reference level.
k\The k in kHz stands for "kilo" = 1000 so 740 kHz = 740,000 Hz. Simple!
The conversion factor from cm-1 to Hz is 3.33564 x 1010 Hz/cm-1.
The sound level in decibels (dB) required for a 1 sone loudness at a frequency of 50 Hz would be around 40 dB. This is because 1 sone is approximately equal to 40 phons, and for a 50 Hz tone, 40 phons is equivalent to around 40 dB SPL (Sound Pressure Level).
The loudness level at 90 dB for a 4000 Hz tone is 7 sones. Sones are a unit of perceived loudness.
The two are not comparable. It's like asking which is more, a mile or a ton.
If you measure amplitude, then it's decibels (dB). If you measure frequency, then it's Hertz (Hz).
Sound is measured in dB ( Decibels) for intensity and or Hz ( Hertz) for frequency or pitch.
The typical range of human hearing is between 20 dB (softest sound) to 120 dB (threshold of pain). However, our sensitivity to different frequencies varies, with our ears being most sensitive to sounds between 2,000 Hz and 5,000 Hz.
In a typical human auditory system, the frequencies that can be heard range from about 20 Hz to 20,000 Hz. Sounds below 20 Hz are considered infrasound, while sounds above 20,000 Hz are considered ultrasound, which are generally inaudible to humans.
20.000 Hz 0 decibels 45.000 Hz -12 decibels 90.000 Hz -24 decibels
RF- Radio Frequency, which is in the measure of kilo & mega Hz range
