Abstract
A method of masking road noise for a vehicle includes monitoring, through a processor, one or more vehicle mounted transducers for noise produced by an interaction between the vehicle and a road surface, detecting, through the processor, an audible signal having one of an undesirable frequency and an undesirable magnitude associated with the interaction between the vehicle and the road surface, generating, through the processor, a masking signal having a frequency that will mask the audible signal having the one of the undesirable frequency and undesirable magnitude, and emitting the masking signal through one or more vehicle speakers.
Claims20
A method of masking road noise for a vehicle comprising:
- monitoring, through a processor, one or more vehicle mounted transducers for noise produced by an interaction between the vehicle and a road surface;
- receiving through at least one of the one or more vehicle mounted transducers an audible signal of the noise produced by the interaction between the vehicle and the road surface;
- determining, through the processor, that the audible signal includes one of an undesirable frequency and an undesirable magnitude associated with the interaction between the vehicle and the road surface;
- generating, through the processor, a masking signal having a frequency that will mask the audible signal having the one of the undesirable frequency and undesirable magnitude;
- and
- emitting the masking signal through one or more vehicle speakers.
A road noise masking system for a vehicle comprising:
- a controller including a non-volatile memory, and a computer processor unit (CPU) having a computer readable program code embodied therewith, the computer readable program code, when executed by the CPU, causes the CPU to:
- monitor, through the CPU, one or more vehicle mounted transducers for noise produced by an interaction between the vehicle and a road surface;
- receive through at least one of the one or more vehicle mounted transducers an audible signal of the noise produced by the interaction between the vehicle and the road surface;
- determine, through the CPU, that the audible signal includes at least one of an undesirable frequency and an undesirable magnitude associated with the interaction between the vehicle and the road surface;
- generate, through the CPU, a masking signal having a frequency that will mask the audible signal having the one of the undesirable frequency and the undesirable magnitude;
- and
- emit the masking signal through one or more vehicle speakers.
A vehicle comprising:
- a body having an exterior portion and an interior portion;
- one or more transducers arranged at one of the exterior portion and the interior portion;
- and
- a road noise masking system arranged in the vehicle, the road noise masking system comprising:
- a controller including a non-volatile memory, and a computer processor unit (CPU) having a computer readable program code embodied therewith, the computer readable program code, when executed by the CPU, causes the CPU to:
- monitor, through the CPU, the one or more transducers for noise produced by an interaction between the vehicle and a road surface;
- receive through at least one of the one or more vehicle mounted transducers an audible signal of the noise produced by the interaction between the vehicle and the road surface;
- determine, through the CPU, that the audible signal includes one of an undesirable frequency and an undesired magnitude associated with the interaction between the vehicle and the road surface;
- generate, through the CPU, a masking signal having a frequency that will mask the audible signal having the one of the undesirable frequency and the undesirable magnitude;
- and
- emit the masking signal through one or more vehicle speakers.
