Method Detail

getAttenuation

public double getAttenuation(double frequency,
                             double phi,
                             double theta)

Returns the attenuation in dB of the directivity pattern at a given angle (phi, theta).

Specified by:

getAttenuation in interface DirectivitySphere

Parameters:

frequency - Frequency in Hertz

phi - (0 2π) with 0 is front

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

Returns:

attenuation in dB

getAttenuationArray

public double[] getAttenuationArray(double[] frequencies,
                                    double phi,
                                    double theta)

Returns the attenuation in dB of the directivity pattern at a given angle (phi, theta).

Specified by:

getAttenuationArray in interface DirectivitySphere

Parameters:

frequencies - Frequency array in Hertz (same order will be returned)

phi - (0 2π) 0 is front

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

Returns:

Attenuation in dB for each frequency

coverFrequency

public boolean coverFrequency(double frequency)

Check if this sphere is capable of producing an attenuation for this frequency

Specified by:

coverFrequency in interface DirectivitySphere

Parameters:

frequency - Frequency in Hertz

Returns:

True
