Odor neutralizing apparatus with integrated noise cancelation system and method

An odor neutralizing unit, comprising:

• a housing defining an inlet, an outlet, and an internal volume extending between the inlet and the outlet;
• an odor neutralizing gas emitter coupled to the housing and configured to provide an odor neutralizing gas that neutralizes odor particles into the internal volume, wherein the odor neutralizing gas emitter generates an emitter noise signal during operation;
• and
• a fan coupled to the housing and configured to draw air into the internal volume through the inlet and expel a mixture of the air and the odor neutralizing gas from the internal volume through the outlet, wherein the fan generates a fan noise signal during operation;
• at least one baffle coupled to the housing and extending into the internal volume, wherein the at least one baffle is configured to attenuate at least one of the emitter noise signal and the fan noise signal.

An odor neutralizing unit, comprising:

• a housing defining an inlet, an outlet, and an internal volume extending between the inlet and the outlet;
• an ozone generator extending within the housing and configured to provide ozone gas that neutralizes odor particles;
• a fan coupled to the housing and configured to draw air into the internal volume through the inlet and expel a mixture of the air and the ozone gas from the internal volume through the outlet, wherein the fan generates a fan noise signal during operation;
• at least one baffle coupled to the housing and extending into the internal volume, wherein the at least one baffle is configured to attenuate the fan noise signal;
• and
• an active noise canceling system, comprising:
• a microphone configured to generate a captured signal representing the fan noise signal;
• a speaker configured to produce sound;
• and
• a controller operatively coupled to the microphone and the speaker and configured to receive the captured signal from the microphone, wherein the controller is configured to control the speaker to emit an anti-noise signal based on the captured signal, and wherein the anti-noise signal is configured to attenuate the fan noise signal.

A method of neutralizing odors, comprising:

• providing, by an odor neutralizing gas emitter, an odor neutralizing gas configured to neutralize odor particles into an internal volume of a housing, the housing defining an inlet and an outlet fluidly coupled to the internal volume;
• moving, by a fan, air into the internal volume through the inlet;
• expelling, by the fan, a mixture of the air and the odor neutralizing gas through the outlet;
• generating, by at least one of the odor neutralizing gas emitter and the fan, a noise signal;
• and
• emitting, by an acoustic transducer, an anti-noise signal configured to attenuate the noise signal generated by the at least one of the odor neutralizing gas emitter and the fan.
