Abstract
A treadmill having a running deck comprising a motor arranged to drive movement of a tread belt, a processor, memory in electronic communication with the processor, and instructions stored in the memory. The instructions are executable by the processor to determine an anti-phase waveform based on waveform attributes of a noise emitted from the treadmill and to cause a sound of the anti-phase waveform to be emitted into a surrounding environment.
Claims20
A treadmill, comprising:
- a running deck comprising a motor arranged to drive movement of a tread belt;
- a speaker incorporated into the running deck;
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- determine an anti-phase waveform based on waveform attributes of both a noise emitted from the treadmill and a noise caused by treadmill use;
- and
- cause a sound of the anti-phase waveform to be emitted into a surrounding environment from a speaker incorporated into the running deck.

A treadmill, comprising
- a running deck comprising a motor arranged to drive movement of a tread belt;
- a microphone incorporated into the treadmill;
- a speaker incorporated into the running deck;
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- determine waveform attributes of a noise emitted from the treadmill and a noise caused by treadmill use and recorded with the microphone;
- generate an anti-phase waveform based on waveform;
- and
- cause a sound of the anti-phase waveform to be emitted into a surrounding environment with the speaker incorporated into the running deck.
8 more elements
A treadmill, comprising;
- a running deck comprising a motor arranged to drive movement of a tread belt;
- a housing covering the motor;
- a microphone incorporated into the running deck;
- a speaker incorporated into the housing;
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- distinguish between motor noise and other noise caused by treadmill use and other types of sounds from a non-treadmill source recorded with the microphone;
- determine waveform attributes of the motor noise and other noise caused by treadmill use;
- generate an anti-phase waveform based on waveform attributes;
- and
- cause a sound of the anti-phase waveform to be emitted into a surrounding environment with the speaker, wherein the anti-phase waveform at least reduces the motor noise and other noise caused by treadmill use.
