Psychological Analysis of Complainants on Noise/Low Frequency Noise and the Relation between Psychological Response and Brain Structure

In Japan there are two kinds of low frequency noise (LFN) problems. One is LFN that can be heard directly in a house and causes discomfort, and the other is LFN that rattles windows or doors and causes annoyance. Authors met about 100 complainants on noise or low frequency noise. Hearing thresholds of some complainants were measured and Yatabe-Guilford personality inventories of some complainants were carried out. We observed many complainants and tried to analyze the complainants' mind by the psychoanalytical method. Their minds have three layers. The 1st layer is the basic desire for survival and good life etc. The 2nd layer is personality or consideration obtained by experience and the 3rd layer concerns movement, speech or action etc. Many complainants lack the 2nd layer on noise/low frequency noise and their movements and reactions on noise/LFN appear directly from the 1st layer of basic desire without consideration of the 2nd layer. The findings of the three layers are discussed in relation to present knowledge on how the different parts of the brain are organized.

The Brain

The electrical activity of the brain recorded by EEG which used to detect different types of diseases and disorders of the human brain. There is contained a large amount of random noise present during EEG recording, such as artifacts and baseline changes. These noises affect the low -frequency range of the EEG signal. These artifacts hiding some valuable information during analyzing of the EEG signal. In this paper we used the FIR filter for removing low -frequency noise(<1Hz) from the EEG signal. The performance is measured by calculating the SNR and the RMSE. We obtained RMSE average value from the test is 0.08 and the SNR value at frequency(<1Hz) is 0.0190.

Mere Presence

A survey of complaints about infrasound and low frequency noise has been carried out. 198 persons reported their troubles in a questionnaire. Their verbal reports often described the sound as deep and humming or rumbling, as if coming from the distant idling engine of a truck or pump. Nearly all respondent's reported a sensory perception of a sound. In general they reported that they perceived the sound with their ears, but many mention also the perception of vibration, either in their body or in external objects. The sound disturbs and irritates during most activities, and many consider its mere presence as a torment to them. Many of the respondents reported secondary effects, such as insomnia, headache and palpitation, which they associtated with the sound mainly because it occured at the same place as the sound. In a majority of the cases, only one or a few persons can hear the sound, but there are also examples, where it is claimed to be audible to everybody. Typically, measurements have shown that existing limits (and hearing thresholds) are not exceeded. The investigation leaves the key question: Are the troubles induced by an external sound or not, and if they are, which frequencies and levels are involved? The feasibility of a study of this is supported by the results.

The Brain

In the UK low frequency noise is a growing problem and complaints from members of the public are rarely resolved. Environmental Health Officers are given inappropriate guidelines and many do not have the necessary training or equipment. As a result technical misconceptions have become institutionalised, exacerbating the problem. Suggestions for dealing with this situation are offered. There is a need for research into the effects upon the brain caused by very low frequency noise (below about 75 Hz), since these are reported to be particularly distressing.
