getDirectionAttenuation

public static Double getDirectionAttenuation(LineSource lineSource,
 double phi,
 double theta,
 double frequency)

Compute the attenuation for the specified noise source and parameters

Parameters:

phi - (0 2π) 0 is front

theta - (-π/2 π/2) 0 is horizontal π is top

frequency - Emission frequency

Returns:

Directional sound power

computeLowSourcePower

public double computeLowSourcePower()

Compute the total acoustic power (in Watts) of low sources (ROLLING, TRACTIONA, AERODYNAMICA) from the railway source list. This is used as the weight for Cref averaging.

Returns:

total power in Watts of the low source types, or 0 if none present

getCref

public double getCref()

Returns:

Reflection coefficient of the vehicle body barrier (0-1), power-weighted average.

setCref

public void setCref(double cref)

Set the reflection coefficient of the vehicle body barrier.

Parameters:

cref - 0 = open freight (no reflection), 1 = fully reflecting body

getCrefTotalWeight

public double getCrefTotalWeight()

Returns:

Accumulated weight for cref averaging

setCrefTotalWeight

public void setCrefTotalWeight(double crefTotalWeight)

Set the accumulated weight for cref averaging.

Parameters:

crefTotalWeight - acoustic power in Watts of low sources
