Noise reduction in decibels Solution

STEP 0: Pre-Calculation Summary
Formula Used
noise_reduction = 10*log10((20*Total height of wall^2)/(Wavelength*Horizontal Distance))
N = 10*log10((20*hw^2)/(λ*R))
This formula uses 2 Functions, 3 Variables
Functions Used
log10 - Common logarithm function (base 10), log10(Number)
log - Logarithm function, log(Number, Base)
Variables Used
Total height of wall - Total height of wall which is under the consideration. (Measured in Meter)
Wavelength - Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire (Measured in Meter)
Horizontal Distance - Horizontal Distance denotes the instantaneous horizontal distance cover by an object in a projectile motion (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Total height of wall: 3 Meter --> 3 Meter No Conversion Required
Wavelength: 2 Meter --> 2 Meter No Conversion Required
Horizontal Distance: 1 Meter --> 1 Meter No Conversion Required
STEP 2: Evaluate Formula
