Masking and Demasking Agents

Masking and Demasking Agents

EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...

Summary

This summary is machine-generated.

Dip listening, aided by amplitude modulation (AM) envelope regularity, is influenced by stimulus context. Temporal pattern analysis of AM peakedness (AMP) between maskers and cursors affects auditory perception.

Area of Science:

Auditory perception
Psychoacoustics
Signal processing

Background:

Amplitude modulation (AM) of maskers can reduce masking for pure-tone targets, suggesting dip listening.
Dip listening efficiency may depend on the temporal context provided by precursor or postcursor stimuli.

Purpose of the Study:

To investigate if dip-listening efficiency is modulated by the match in AM peakedness (AMP) between a masker and surrounding stimuli.
To explore the role of temporal pattern analysis in auditory perception of modulated sounds.

Main Methods:

Masked thresholds for pure-tone targets were measured in normal-hearing listeners.
Schroeder-phase harmonic complexes with varying AMP were used as maskers and cursors.
Temporal gaps and frequency differences (F0) between stimuli were manipulated.

Main Results:

Threshold elevation (interference) occurred with flat cursors and peaked maskers, indicating proactive and retroactive temporal analysis.
Threshold decline (facilitation) was observed when masker AMP matched the precursor, suggesting proactive processing.
Interference and facilitation persisted with temporal gaps but disappeared with F0 differences, and decreased with reduced levels.

Conclusions:

Envelope regularity plays a significant role in dip listening, particularly when masker and cursor are F0-matched, forming a single perceptual stream.
These findings suggest a time-domain form of comodulation masking release, influenced by temporal pattern analysis of AM envelope characteristics.
