Constructor Detail

SoundSensor

public SoundSensor(SensorPort sensor)

Used to detect the loudness of sounds in the environment.

Parameters:

sensor - e.g. Port.S1

Method Detail

getdB

public int getdB()

Returns the decibels measured by the sound sensor.
e.g. Whispering = 20 dB
Vacuum cleaner = 80 dB
Jet engine = 150 dB
NOTE: Uncertain if PCTFILLSCALEMODE is producing accurate dB values.

Returns:

dB - decibels

getdBA

public int getdBA()

Returns sound within the human hearing frequency range, normalized by A-weighting. Extremely high frequency or low frequency sounds are not detected with this filtering (regardless of loudness).

Returns:

dB(A) - decibels with A-weighting
