Bose uses its noise reduction technology to stop car rides

Bose uses its noise reduction in cars to block road noise (and even stops you from squealing and rattling while your car is getting older)

  • New system uses accelerometers and microphones to measure vibrations
  • Software then sends an & # 39; acoustic cancellation signal & # 39; to the loudspeakers of the car

Bose wants to use the noise-canceling technology in its headphones to block sounds from external cars.

The leading audio brand has developed a way to eliminate noise caused by rough roads, using accelerometers and microphones to measure vibrations.

Software and algorithms can then calculate an acoustic cancellation signal that is played through the car's speakers to reduce unwanted noise.

HOW IT WORKS

Accelerometers on the body of the vehicle ensure that a Bose algorithm continuously measures vibrations that cause noise.

This information is then used to calculate an acoustic cancellation signal, which is output from the vehicle's speakers to reduce the target noise.

Microphones placed in the cabin monitor the remaining sound levels, allowing the system to adjust the control signal for optimum performance over different road surfaces, and automatically adjust over time as the vehicle ages.

Today, many car manufacturers use thick insulation and modified tires as a way to combat external noises, but Bose says these approaches are not only less effective, but can also increase vehicle weight and reduce fuel efficiency.

The move is the latest attempt by the company to reduce the noise level in vehicles.

Since 2010, it has used its technology to tackle engine noises.

"For years we were asked why we can not easily adapt our noise canceling headphone technology to vehicle cabs for a quieter driving experience," said John Feng, manager of Bose's sound management solutions.

& # 39; But we know that it is much more difficult to control the sound in a large space like an autocab in comparison to the relatively small area around your ears.

& # 39; However, through research and our unremitting efforts to solve difficult problems, we have achieved a level of road noise reduction that distinguishes Bose from competitive offers. & # 39;

Bose says that the solution will be available to manufacturers, regardless of whether they use their own sound system in the car, with the first models using QuietComfort RNC expected to be in production by the end of 2021.
