Height of Barrier Wall given Noise Reduction in Decibels Solution

STEP 0: Pre-Calculation Summary

Formula Used

Height of the Barrier Wall = sqrt(((Wavelength of Sound Wave*Horizontal Distance)/20)*10^(Noise Reduction/10))
h_w = sqrt(((λ*R)/20)*10^(N/10))
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

Wavelength of Sound Wave: 0.6 Meter --> 0.6 Meter No Conversion Required
Horizontal Distance: 1.01 Meter --> 1.01 Meter No Conversion Required
Noise Reduction: 25 Decibel --> 25 Decibel No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_w = sqrt(((λ*R)/20)*10^(N/10)) --> sqrt(((0.6*1.01)/20)*10^(25/10))

Evaluating ... ...

h_w = 3.09543233011323

STEP 3: Convert Result to Output's Unit

3.09543233011323 Meter --> No Conversion Required

FINAL ANSWER

3.09543233011323 ≈ 3.095432 Meter <-- Height of the Barrier Wall
