30 Nov 2003 | Experiments on a stereo speech database contaminated with noise show that the PARAT microphone compares favourably with a high-quality noise-cancelling close-talking microphone. |
| The results provide documented evidence for the use of noise reduction headphones for task attention. | |
| The results show that depending on the recording situation the noise cancelling approach applied to a microphone array system leads to a significant enhancement of the signal to noise ratio of the array output signal. | |
01 Dec 2017 | Although the noise canceling headphones and earphones can reduce factory noise, but they prevent verbal communications and give uncomfortable feeling, so headrest ANC systems becomes one of candidates for this kind of situations. |
| In this human study, we provide evidence for a top-down type of tinnitus associated with a deficient noise-cancelling mechanism. | |
35 Citations | The results indicate the use of noise cancelling headphones, without any conflicting in ear audio signal, aided participants’ ability to hear and recall information. |
110 Citations | An analysis of the noise sources affecting MRS signals show that the applicability of adaptive noise cancelling is primarily limited to cancel powerline harmonics. |
99 Citations | We show that noise cancelling can be improved if the multiple origins of noise are taken into account. |
| The results also supported previous research that reflects positively on the benefits of noise cancelling headphones in reducing the effects of noise on performance especially for non-native English speakers. | |
| The beneficial effects of noise cancelling headphones in improving the signal to noise ratio led to an improved performance for nonnative speakers. | |
23 Citations | Experimental results show that the new system is able to accurately preserve desired internal sound while cancelling uncorrelated external noise. |
| The results indicate that coupler responses and dummy-head responses are not identical to actual-ear responses in most models, open-air type headphones have poor sound shielding ability, and the harmonic distortion and phase characteristics of all headphones tested are not problematic. | |
| The noise-cancelling performance conforms closely to theory. | |
| Experimental results show that the developed system can preserve the auxiliary audio sound while cancelling external noise effectively. | |
| Experimental results show that the developed light-weight ANC earphones achieve higher noise reduction than the commercial ANC headphones and earphones, and the in-ear ANC earphone has the best noise reduction performance. |

How to design or develop noise cancellation headphones?4 answersNoise cancellation headphones can be designed or developed by following certain steps. First, the headphones should have vibration members connected to an audio input within the housing of an earcup. These vibration members are responsible for generating sound waves that cancel out external noise. Additionally, the headphones should have front covers and rear covers connected to form front cavities, with air-releasing holes to maintain consistent air pressure and ensure effective noise cancellation. Furthermore, the headphones should include an electrodynamic speaker with ventilation openings and an acoustically permeable front panel, along with a microphone and electronics for active noise cancellation. Another important feature is the presence of a front vent opening in close proximity to the microphone, which allows the microphone to be used as a feedback microphone for active noise cancellation. Finally, a noise cancellation system for the headphones should include multiple noise filters, a combiner, and an adaptation engine to process and adjust the noise signals based on the leakage condition of the audio device.
What is Noise Cancellation.?3 answersNoise cancellation is a technique used to reduce or eliminate unwanted noise from an audio signal. It involves generating an inverted signal that cancels out the ambient noise when combined with the original signal. The process of noise cancellation can be achieved through various methods and devices. One approach is to determine a noise cancellation parameter based on factors such as the level of noise or the match between an earpiece and an ear canal. Another method involves measuring the distance between the noise source and an object, generating a reverse phase signal of the noise, and producing an anti-noise signal based on the distance information. Additionally, a noise cancellation device can utilize different transfer functions to process a digital signal and generate a noise cancellation signal. Another system uses multiple noise filters, a combiner, and an adaptation engine to estimate the leakage condition of an audio device and adjust the gain factors accordingly. Overall, noise cancellation aims to improve the quality of audio by reducing unwanted background noise.
