TL;DR: The results showed that subjects' preference for visual images was significantly related to NF, the number of land types, and the A-weighted equivalent sound pressure level, and LAeq and NF were the dominant factors affecting the annoyance from high-speed train noise in the combined audio-visual condition.

TL;DR: In this article, an auditory experiment was carried out to investigate the relationship between various level indices and subjective responses to floor impact sounds and it was found that sound quality ratings (LL z and N max ) as well as instrumental metrics (L Aeq, L Amax and L m, 1/1/1(63−500) ) showed good correlation with impact sound annoyance.
Abstract: Measurements of impact sounds generated by an impact ball (heavy/soft impact source) were conducted in apartment buildings with box-frame type reinforced concrete structures. Variations in frequency characteristics were found in the impact ball sounds and these were classified into three frequency groups. An auditory experiment was carried out to investigate the relationship between various level indices and subjective responses to floor impact sounds. It was found that sound quality ratings (LL z and N max ) as well as instrumental metrics (L Aeq , L Amax and L m,1/1(63―500) ) showed good correlation with impact sound annoyance. Among them, L Amax was suggested as a practical descriptor of the auditory sensation of impact ball sounds on the basis of measurement and calculation procedures. Additional auditory experiments were conducted to characterize the classified impact sound groups and to evaluate the annoyance of impact ball sounds through paired comparison and semantic differential tests. The results show that the impact ball sound with a dominant sound pressure level at 250 Hz was most annoying. Sound Quality (SQ) metrics were used to explain the annoyance level of heavy-weight floor impact sounds. The annoyance obtained from the paired comparison test correlated well with loudness and fluctuation strength. In the semantic differential test, it was found that the adjectives describing loudness had a dominant effect on the subjects' annoyance levels.

TL;DR: Both noise annoyance and Lden showed independent associations with asthma symptoms among asthmatics, especially in those reporting adult-onset asthma, which suggests both psychological and physiological noise reactions on the respiratory system, and could be relevant for asthma care.

TL;DR: The results show that high levels of noise are particularly disruptive for dual-task paradigms, requiring attention sharing, and sequential responding, involving speed and accuracy, and both the level and the type of noise background affect memory.
Abstract: This paper is an overview of research on the extra-auditory effects of exposure to noise. The aim is to demonstrate the pervasiveness of the effects in support of noise reduction at the source for reasons that go well beyond hearing conservation. The areas discussed are performance effects, including vigilance, selective attention, sensory-motor behavior and memory; physical effects, including cardiovascular disease and sleep-related disorders, and annoyance, with special reference to psychological outcomes. The results show that high levels of noise are particularly disruptive for dual-task paradigms, requiring attention sharing, and sequential responding, involving speed and accuracy. Both the level and the type of noise background affect memory, severely limiting the number of stimulus dimensions that may be simultaneously encoded and retained. Community noise with a preponderance of heavy traffic and aircraft flyovers affects sleep, resulting in changes in the normal pattern of EEG fluctuations, and increases in movement and heart rate. Lastly, noise causes annoyance, with its own set of by-products: job dissatisfaction, irritability and anxiety over potential risk.

TL;DR: In this paper, the authors carried out measurements to evaluate industrial noise levels, are these levels exceeded the permissible levels set by Egyptian noise standard and policy to protect public health of workers?, to examine worker's attitudes towards industrial noise, to know the relationship between industrial noise level and degree of annoyance.
