Abstract
A gaming machine in a gaming establishment enhances its game sounds by attenuating ambient noise in the establishment. The gaming machine includes a microphone, processing circuitry, and an audio speaker. The microphone detects ambient noise and generates a noise signal from the sensed ambient noise. The processing circuitry generates an anti-noise signal from the noise signal and adds the anti-noise signal to a game sound signal generated by the gaming machine to produce an output signal. The audio speaker is driven with the output signal.
Claims13
A method of enhancing game sounds generated by a gaming machine operating in a gaming establishment, comprising:
- detecting ambient noise in the gaming establishment with a microphone mounted to the gaming machine;
- generating a noise signal from the sensed ambient noise;
- processing the noise signal to generate an anti-noise signal;
- and
- driving an audio speaker with an output signal comprised of the anti-noise signal.
A gaming machine operating in a gaming establishment, comprising:
- means for detecting ambient noise in the gaming establishment and generating a noise signal from the sensed ambient noise;
- means for processing the noise signal to generate an anti-noise signal;
- and
- an audio speaker driven with an output signal comprised of the anti-noise signal.
