ACTIVE NOISE REDUCTION HEADPHONES AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18400971 titled 'ACTIVE NOISE REDUCTION HEADPHONES AND METHOD
Simplified Explanation
The abstract describes a patent application for Active Noise Reduction (ANR) headphones that use multiple sensors to generate a composite compensation signal for improved noise cancellation.
- ANR headphones include a loudspeaker, external microphone for ambient noise detection, internal microphone for residual noise detection, and an acceleration sensor.
- The controller generates a loudspeaker signal based on a composite compensation signal, which combines ambient noise, residual noise, and acceleration compensation signals.
Potential Applications
The technology can be applied in various industries such as aviation, automotive, and consumer electronics for improved noise cancellation in headphones and communication devices.
Problems Solved
1. Improved noise cancellation in headphones by utilizing multiple sensors for accurate compensation signals. 2. Enhanced user experience by reducing ambient noise, residual noise, and noise caused by user movements.
Benefits
1. Better audio quality in noisy environments. 2. Increased comfort for users by reducing unwanted noise. 3. Enhanced safety in critical environments by minimizing distractions.
Potential Commercial Applications
Optimizing noise cancellation technology in headphones for consumer electronics market with a focus on high-quality audio experiences.
Possible Prior Art
Prior art may include existing noise cancellation technologies in headphones and communication devices that use single or limited sensors for noise compensation.
Unanswered Questions
How does the composite compensation signal improve noise cancellation compared to traditional methods?
The composite compensation signal combines multiple sources of noise data to provide more accurate and effective noise cancellation, resulting in improved audio quality for the user.
What are the limitations of the current ANR headphone technology?
The current technology may have limitations in accurately detecting and compensating for all types of noise sources, especially in complex and dynamic environments. Further research and development may be needed to address these limitations.
Original Abstract Submitted
ANR headphones generate a sound signal, and include a loudspeaker, an external microphone configured to detect an ambient noise signal, and an internal microphone configured to detect a residual noise signal within an ear canal of the user. Moreover, the ANR headphones have an acceleration sensor configured to generate an acceleration signal indicative of accelerations experienced by the ANR headphones. A controller of the ANR headphones is configured to generate a loudspeaker signal based on a composite compensation signal. The composite compensation signal is a combination of an ambient noise compensation signal based on the ambient noise signal, a residual noise compensation signal based on the residual noise signal and an acceleration compensation signal based on the acceleration signal.
