Height of Barrier Wall given Noise Reduction in Decibels Solution

STEP 0: Pre-Calculation Summary

Formula Used

Height of Crack = sqrt((Wavelength*Horizontal Distance/20)*10^(Noise reduction/10))
h = 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 Crack - (Measured in Meter) - Height of Crack is the size of a flaw or crack in a material that can lead to catastrophic failure under a given stress.
Wavelength - (Measured in Meter) - Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
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

Wavelength: 2.1 Nanometer --> 2.1E-09 Meter (Check conversion here)
Horizontal Distance: 1.01 Meter --> 1.01 Meter No Conversion Required
Noise reduction: 65 Decibel --> 65 Decibel No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h = sqrt((λ*R/20)*10^(N/10)) --> sqrt((2.1E-09*1.01/20)*10^(65/10))

Evaluating ... ...

h = 0.0183128246281358

STEP 3: Convert Result to Output's Unit

0.0183128246281358 Meter -->18.3128246281358 Millimeter (Check conversion here)

FINAL ANSWER

18.3128246281358 ≈ 18.31282 Millimeter <-- Height of Crack
