Over the past 50 years, the A-weighted sound pressure level (dBA) has become the predominant measurement used in noise analysis. This is in spite of the fact that many studies have shown that the use of the A-weighting curve underestimates the role low frequency noise plays in loudness, annoyance, and speech intelligibility. The intentional de-emphasizing of low frequency noise content by A-weighting in studies can also lead to a misjudgment of the exposure risk of some physical and… Expand

Loudness experiment on general environmental noises considering low-frequency components down to infrasound
Wind turbine noise has become a serious environmental noise issue. To investigate this problem, a research project has been conducted over the three years from fiscal year 2010. In this project,… Expand
Airborne sound insulation in terms of a loudness model
Abstract One of the main goals of building acoustics is the prediction of airborne sound insulation between rooms to determine the quality of sound protection. In many practical cases, however, the… Expand
A STUDY UPON OCCUPATIONAL NOISE POLLUTION EXPOSURE AT A METALLIC CONFECTIONS PLANT
Because of physical and psychological effects, hearing damage, in the main concern of safety regulations, should not be neglected. There are provable psychological reactions (strain, anger) and… Expand
Use of Helmholtz resonators for noise attenuation
Acoustics is the only category in which a LEED-rated office building performs worse than a conventional building. The exposed hard surfaces and the lack of partitions cause easy propagation of… Expand
Low Frequency Noise from Transportation Sources
Low frequency noise (LFN) is common as background noise in urban environments and as an emission from many artificial sources: road vehicles, aircraft, industrial machinery, artillery and mining… Expand
Chapter 2 – Principles of Environmental Noise
This chapter introduces the basic principles of environmental noise. At the outset the difference between the terms ‘noise’ and ‘sound’ is discussed followed by the general theory informing the wave… Expand
Subjective Estimation of Airborne Sound Insulation
This study explores airborne sound insulation as an objective and subjective measure. The concept of this study starts with a hypothesis that there is a need to assess airborne sound insulation in… Expand
Understanding and improving the perception of a hospital ward soundscape
The various aspects of hospital environments have been shown to affect individuals psychologically and physiologically. One aspect of this, sound, has been thoroughly documented through acoustic… Expand
The effects of physical vibration on heart rate variability as a measure of drowsiness
TLDR
Characteristic changes in heart rate variability (HRV) domains that indicated progressively increasing neurological effort in maintaining alertness in response to low frequency vibration, which becomes significant within 30 min are found. Expand
Misperceptions of the Emotional Content of Natural and Vocoded Speech in a Car
TLDR
Experimental results show that the recognition rates for emotions and perceived emotional strength degrade as signal-to-noise ratio decreases, and misperceptions seem to be more pronounced for negative and lowarousal emotions such as calmness or anger, while positive emotions appear to beMore robust to noise.

Evaluation of loudness-level weightings for assessing the annoyance of environmental noise.
TLDR
In terms of correlation with subjective judgments of annoyance-not loudness-the LLSEL formulation performs much better than do the loudness calculations, which is true across a range of sources that includes aircraft, helicopters, motor vehicles, trains, and impulsive sources. Expand
The Effects of Broadband, Tonal and Masked Ventilation Noise on Performance, Wakefulness and Annoyance
TLDR
Comparisons between the masked ventilation noise and the tonal ventilation noise masked by means of a pink noise showed that the Masked ventilation noise was correlated to ambiguous tendencies towards higher performance, lower fatigue but higher annoyance. Expand
Sources and effects of low-frequency noise.
TLDR
Evidence suggests that a number of adverse effects of noise in general arise from exposure to low-frequency noise: Loudness judgments and annoyance reactions are sometimes reported to be greater for low- frequency noise than other noises for equal sound-pressure level. Expand
Low frequency noise "pollution" interferes with performance.
TLDR
The results suggest that the quality of work performance and perceived annoyance may be influenced by a continuous exposure to low frequency noise at commonly occurring noise levels and subjects categorised as high-sensitive to low Frequency noise may be at highest risk. Expand
Why can a decrease in dB(A) produce an increase in loudness?
TLDR
The analysis shows that loudness patterns produced in the auditory system by the tone-noise complex can account for the observed effects and shows that the A-weighting and the loudness of the complex are negatively related. Expand
Temporary Threshold Shift in Hearing from Exposure to Different Noise Spectra at Equal dBA Level
The intent of this study was to determine whether sound‐level measurements in dBA could adequately depict harmfulness to hearing from exposures to noises differing widely in spectra. Each of 11 male… Expand
Loudness Assessment of Band Noise of Varying Bandwidth and Spectral Shape. An Evaluation of Various Frequency Weighting Networks
The ability of different evaluation methods to predict loudness was assessed. In Experiment I, 12 subjects matched a band noise (900–1060Hz) to equal the loudness of each of 45 different noises… Expand
Effects of occupational exposure to low frequency noise on cognition.
TLDR
It is suggested that prolonged exposure to LPALF noise might contribute to cognitive impairment and that the P300 event-related brain potential recording may be a valuable diagnostic tool. Expand
Changes in Wakefulness during Exposure to Noise at 42 Hz, 1000 Hz and Individual EEG Frequencies
This report includes two investigations. Investigation 1 was carried out in order to study the correlation between changes in wakefulness and exposure to low frequency and high frequency noise. The… Expand
High-Frequency Hearing Loss Incurred by Exposure to Low-Frequency Noise,
TLDR
It is concluded that low-frequency noise produces permanent high-frequency hearing loss in chinchillas and the human ear shows a similar pattern of temporary threshold shift, and the current damage-risk criteria may be inadequate and may require revision to deal with high-intensity, low- frequencies.
