I know nothing about sound frequency, so when I see things like Hz, I am at a loss as to what's being talked about. I really want this specific question answered, included with any additional information that may help me understand sound frequency in the future.

Hz (hertz) is simply a measurement of frequency. Low Hz means you have a low tone (a bass tone) while high Hz means you have a high pitch sound. You see, all sound is is just vibrations in the air. These vibrations can be viewed as waves with peaks and valleys. Now, there is a certain amount of time between each peak. This determines what the frequency of the sound is. A high frequency sound will have a very short amount of time between each peak.
Imagine your car engine if you will. As you hit the throttle it makes a higher and higher pitch noise right? Simplified, this noise is made by each cylinder firing. As they fire faster and faster, the peaks (the "pop" each cylinder makes) grow closer and closer, making the engine sound higher pitched.
Now, the Hz has nothing to do with the volume of the sound. Decibels (dB) are a measure of the intensity of sound. The higher the decibel is, the louder it is. However, this is a slightly confusing measurement because it acts in what we call a logarithmic fashion. For example, this means that instead of 2 dB being twice as loud as 1 dB, it is 10 times as loud. 3 dB is 100 times as loud as 1 dB. 4 dB is 1000 times as loud. Now the ACTUAL numbers are not these. This is just an example.
In the end dB is the measure of volume. The higher, the louder.
Now, the human hearing has a certain range of Hz that it can hear. Normally, the human hearing can be said to range from 20 Hz to 2000 Hz (or 2 kHz). This means that 50 Hz is right at the bottom of the hearing range, and some people may not be able to hear it at all. Additionally, higher pitch sounds "sound" louder to us than lower pitch ones of the same dB rating.

Sound travels in a wave (like the swell of the ocean) symbols like Hz refer to the frequency or speed of the wave how many times per second the wave oscillates or vibrates - goes up and down. The hz has nothing to do with how loud a sound is. The loudness is measured in decibles.

Hertz is a measurement of frequency--i.e., 50 waves per second. A 50-hertz sound is on the low end of our hearing spectrum so it would have a bass like tone. The loundness of the sound would depend on the wave amplitude or the amount of energy in the wave.

frequency doesnt have direct relation to loudness.frequency means how bass or treble a sound is . for example 50hz is very bass and it cant maybe heard by some ears .we can hear frequencies about nearly100Hz to 30 Khz i cant remember the exact numbers .for example 12KHz is very treble.frequency has an indirect relation between loudness but for you its still soon to know.you can contact me if you want more detail

It has a relatively long wavelength (for sound). 13th lowest note on a piano. You cannot tell loudness from a frequency. Cheers!

50 Hz not very loud because human speech ranges from 300 to 4000 Hz. see this site for more information if you want........
