Wavelength of Sound given Noise Reduction in Decibels Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wavelength of Sound Wave = (20*Height of the Barrier Wall^2)/(Horizontal Distance*10^(Noise reduction/10))
λ = (20*h_w^2)/(R*10^(N/10))
This formula uses 4 Variables

Variables Used

Wavelength of Sound Wave - (Measured in Meter) - The wavelength of sound wave is the distance between successive points of identical phase, such as between two consecutive compressions or rarefactions.
Height of the Barrier Wall - (Measured in Meter) - The height of the barrier wall is the vertical distance from its base to its top edge.
Horizontal Distance - (Measured in Meter) - Horizontal Distance is the instantaneous horizontal distance cover by an object in a projectile motion.
Noise reduction - (Measured in Decibel) - Noise reduction is the process of removing noise from a signal.

STEP 1: Convert Input(s) to Base Unit

Height of the Barrier Wall: 3.1 Meter --> 3.1 Meter No Conversion Required
Horizontal Distance: 1.01 Meter --> 1.01 Meter No Conversion Required
Noise reduction: 25 Decibel --> 25 Decibel No Conversion Required
