Speech Interference

The desire for a quieter environment, office, or workplace is nearly universal. The technology exists to accurately measure noise emission and estimate the health, functional, and financial impacts on hearing conservation, speech interference, and residential or workplace comfort. Several useful methods for labelling of noise emission have been proposed over the years. Government regulations for certain classes of equipment are already in place in some countries. Why then after several decades of concerted effort is "Selling and Buying Quiet" not commonplace? It may be that the fault lies neither with the quality of the engineering work nor the existence or lack of regulation. Instead, a complex of societal factors including confusion, misinformation, denial, and cognitive dissonance effectively undercut any program. This paper will discuss the societal factors opposing the success of "Selling and Buying Quiet", as experienced by the author, along with some possible approaches for increasing the recognition of noise control engineering in the future.

Speech Interference

Cost-effective noise reduction techniques for historic buildings can be accomplished affordably and without altering the structure's historic status. Techniques include adding sashes to existing historic windows, replacing windows with visually compatible acoustic units, and using jamb extensions to accommodate manufacturers' standard window units. Wood-truss roofs can be insulated from noise on the interior through the addition of a light-gauge metal framing support with alternating layers of gypsum board, plywood, and batt insulation. Ventilation solutions include a unique over-the-sill air intake system that functions as an acoustic baffle and visually spares a historic facade from random louver punch-throughs. Acoustically rated doors and vestibule construction address noise reduction at entry ways. At an example installation, sound levels were reduced by 12 dB, and speech interference levels were reduced by 18–23 dB. Continuous use is the best method for preservation of historic buildings. Noise reduction, sensibly applied, gives a historic structure occupational viability in the modern world.

Abstract Objective This study aimed to investigate the effect of hearing protection devices (HPDs) on speech intelligibility in Persian work environments. Three current earmuffs and three earplugs and one of the prototypes of molded earplug were tested on 15 male subjects which were randomly selected. The noise reduction of HPDs was measured based on the Real Ear Attenuation at Threshold (REAT) method. Speech intelligibility during using HPDs was determined based on the speech discrimination score (SDS) at two signal to noise (S/N) ratios (0 and + 5). Data were analyzed using SPSS 22. Results The actual to nominal noise reduction rating values were from 47 to 84% for HPDs. At two S/N ratios, no significant differences were observed in speech intelligibility using HPDs (p > 0.05). At S/N ratio = 0, the speech intelligibility descriptively has been only improved by using common earmuffs up to 9.07%. There was a significant difference up to 21.27% in speech intelligibility for proposed molded earplugs at S/N ratio = 0 (p < 0.05). Increasing the HPDs' noise attenuation values led to an increase in speech interference (p < 0.05). The HPDs with the minimum required noise attenuation while maintaining acceptable speech intelligibility should be worn by employees exposed to medium noise levels.

The paper deals with the question of the role and significance of service parts of speech both in Lezghin and Russian parts of bilingual Lezghin-Russian dictionary. Prepositions, unions, particles, as well as service morphemes, prefixes and endings play no less important role in lexicography than significant parts of speech. Interference phenomena in Dagestan linguistics affect all language levels both in oral and written forms. The root cause of this phenomenon is the diversity of languages. The following factual and logical examples from the hand-written version of the Lezghin-Russian dictionary that we are editing clearly demonstrate the phenomena of interference in the service parts of speech, inadequate translations into Russian that cannot take place in lexicographical works.
