Potential Acoustic Masking of Greater Sage-grouse (centrocercus Urophasianus) Display Components by Chronic Industrial Noise
—Anthropogenic noise can limit the ability of birds to communicate by masking their acoustic signals. Masking, which reduces the distance over which the signal can be perceived by a receiver, is frequency dependent, so the different notes of a single song may be masked to different degrees. We analyzed the individual notes of mating vocalizations produced by Greater Sage-Grouse (Centrocercus ur...
متن کاملMasking redux. I: An optimized masking method.
This is the first in a series of two papers on masking. The objective of these papers is to develop a masking protocol that provides valid measures of threshold and is, in general, faster than the plateau method. In this paper, a masking method is developed that can replace the traditional plateau method in most masking situations. This new method is optimized to require fewer masking levels th...

متن کاملMatrix Masking
where A is a matrix that operates on the n cases, B is a matrix that operates on the p variables, and C is a matrix that adds perturbations or noise. Matrix masking includes a wide variety of standard approaches to SDL: (i) adding noise, i.e., theC in matrix masking transformation of equation [1]; (ii) releasing a subset of observations (delete rows from Z), i.e., sampling; (iii) cell suppressi...
متن کاملMasking by object substitution: dissociation of masking and cuing effects.
In a newly discovered form of visual masking, a target stimulus is masked by 4 flanking dots if their offset is delayed relative to the target (V. Di Lollo, J. T. Enns, & R. A. Rensink, 2000). In Di Lollo et al. (2000), the dot pattern also cued the relevant target and therefore required deliberate attention. In the present Experiments 2-6, a central arrow cued 1 of 2 letters for an E/F discrim...
