A Perceptual Approach to Reduce Musical Noise Using Critical Bands Tonality Coefficients and Masking Thresholds
Traditional noise reduction techniques have the drawback of generating an annoying musical noise. A new scheme for speech enhancement in high noise environment is developed by considering human auditory system masking characteristics. The new scheme considers the masking threshold of both noisy speech and the denoised one, to detect musical noise components. To make them inaudible, they are set...
متن کاملPerceptual musical noise reduction using critical bands tonality coefficients and masking thresholds
Speech enhancement techniques using spectral subtraction have the drawback of generating an annoying musical noise. We develop a new post-processing method for reducing it in each critical-band. In the proposed technique, the difference between tonality coefficients of the noisy speech and the denoised one constitutes one step for detection. Next, using a modified Johnston masking threshold, we...
متن کاملThe masking of octave-band noise by broad-spectrum noise: a comparison of infant and adult thresholds.
Localization responses to a 4,000-Hz octave-band noise in a background of broad-spectrum noise were obtained from infants, 6, 12, 18, and 24 months of age, and adults. A twoalternative, forced-choice procedure was used to determine thresholds at each of two levels of masking noise, 42 and 60 dBC. Adults were also tested for their localization of pure tones in noise and their detection of octave...
متن کاملNoise frame duration, masking potency and whiteness of temporal noise.
PURPOSE Because of the limited contrast range, increasing the duration of the noise frame is often the only option for increasing the masking potency of external, white temporal noise. This, however, reduces the high-frequency cutoff beyond which noise is no longer white. This study was conducted to determine the longest noise frame duration that produces the strongest masking effect and still ...
متن کاملNoise Suppression Using Active Noise Control and Masking
This paper attempts to make the public/workplace environment more pleasant by combining techniques of active noise control (ANC) and the limited ability of the human auditory system to register a sound in the vicinity of another sound of sufficiently higher intensity. The paper examines the limitations of ANC and masking techniques, and proposes a way to integrate these techniques. A process fo...
