How to calculate frequency?

So, the frequency of the wave is 4 Hz.

0.20 Hz

Wave frequency can be measured by counting the number of crests or compressions that pass the point in 1 second or other time period. The higher the number is, the greater is the frequency of the wave. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second.

Frequency of a wave is given by the equations:

1. f=1T. where: f is the frequency of the wave in hertz. T is the period of the wave in seconds.
2. f=vλ where: f is the frequency of the wave in hertz. v is the velocity of the wave in meters per second. λ is the wavelength of the wave in meters.
3. f=cλ Related topic.

1. Make sure they have the same length unit.
2. Divide the wave velocity by the wavelength.
3. Convert the result to Hertz. 1/s equals 1 Hertz.

Sub-bass sounds are the deep, low-register pitches below approximately 60 Hz (C2 in scientific pitch notation) and extending downward to include the lowest frequency humans can hear, approximately 20 Hz (E0). In this range, human hearing is less sensitive, so these notes tend to be felt more than heard.

How to Make Subwoofers Hit Harder

1. Choose the correct amplifier for the subwoofer. Every type of subwoofer requires a certain power output by an amplifier.
2. Install the subwoofer in a bandpass box.
3. Adjust the settings on the amplifier and stereo unit to accommodate the subwoofer.

The hardest hitting best 10 inch subs is the Planet Audio AC10D ten Inch automobile Subwoofer that has a max power output of 400 w rms , 1000 watts , 1500 watts to 1800 watts. Keep in mind that although this rating isn’t for long-term good sound production, the RMS is still an impressive 900 RMS.

Subwoofers should not get louder as they break-in. Instead, they will adjust to the varying frequencies provided and will most effectively play the sounds that are coming through.
