Forward masking is traditionally measured with a detection task in which the addition of a preceding masking sound results in an increased signal-detection threshold. Little is known about the influence of forward masking on localization of free-field sound for human or animal subjects. When the masking sound precedes the masked sound, it is called forward masking. When the masking is backwards, the masking sound comes milli-seconds after the masked sound. When the masking and masked sounds come at the same time, masking is simultaneous.

Louder sounds can produce less forward masking: Effects of component phase in complex tonesa) Hedwig Gockelb) CNBH, Department of Physiology, University of Cambridge, Downing Street, Cambridge CB2 3EG, England Brian C. J. Moore Department of Experimental Psychology, University of Cambridge, Downing Street, Cambridge CB2 3EB, England Roy D. Patterson CNBH, Department of Physiology, University The ASA definition of masking does not address non-simultaneous masking. Sometimes a signal can be masked by a sound preceding it, called forward masking, or even by a sound following it, called backward masking. Forward masking results from the accumulation of neural excitation, which can occur for up to 200 msec. The influence of the degree of envelope modulation and periodicity on the loudness and effectiveness of sounds as forward maskers was investigated. In the first experiment, listeners matched the loudness of complex tones and noise.

Upward spread of masking is low-frequency sounds masking high-frequency sounds. excitation evoked in the auditory system is forward masking. The threshold of a sinusoidal signal in forward masking is assumed to be monotonically related to the excitation evoked Cite this paper as: Meddis R., Sumner C., Shore S. (2005) Effects of contralateral sound stimulation on forward masking in the guinea pig. 2011-08-28 · Backmasking is the process of reversing an audio signal and placing it in a something meant to be played forwards.

(2002) [5]. They found that optimum spectrum, considering both speech privacy and comfort, is close to sound spectrum, where sound pressure level Simultaneous room reflection masking: Effect of forward fringe and direct sound duration Jörg M.

A proper sound masking system functions entirely in the background, outside of conscious sight, and – more importantly – conscious earshot.

When the masking and masked sounds come at the same time, masking is simultaneous. Upward spread of masking is low-frequency sounds masking high-frequency sounds. forward masking; free-ﬁeld; ILD; ITD; localization IN AUDITION, MASKING REFERS to the ability of an additional sound to interfere with the perception of a target sound. With regard to the timing of the masker and the target, there are three general classes of masking: simultaneous, forward, or backward.
