Non-specific building-related symptoms (NBRSs) describe various symptoms in those affected. Questionnaires are the first step in investigating suspected NBRSs in office environments and have been used for over two decades. However, changes in reporting of symptoms among office workers over time are currently unknown. The overall aim was thus to inv...
The aim of this study is to compare vibration exposure to noise exposure from railway traffic in terms of equal annoyance, i.e., to determine when a certain noise level is equally annoying as a corresponding vibration velocity. Based on questionnaire data from the Train Vibration and Noise Effects (TVANE) research project from residential areas exp...
Epidemiological studies on sleep often use questionnaires, and measurement of validity provides necessary guidance in selection of valid single sleep questions. Twenty-five items assessing different aspects of sleep, including overall sleep quality, specific sleep parameters, nocturnal restoration, and exposure-related questions, were tested. This...
In a residential area exposed to road traffic noise a socio-acoustic longitudinal study was conducted to investigate the effects of a large intervention project on acoustical conditions and resident's noise responses. The paper presents results on general noise annoyance, noise disturbed activities and perceptions of the sound environment in relati...
Undisturbed sleep is essential for physiological and psychological health. Children have a special need for
uninterrupted sleep for growth and cognitive development. Noise is an environmental factor that affects most
children, but the knowledge of how children's health, wellbeing and cognitive development are affected by noise
disturbed sleep due t...
Undisturbed sleep is essential for physiological and psychological health. Children have a special need for uninterrupted sleep for growth and cognitive development. Noise is an environmental factor that affects most children. In addition to noise in schools and preschools, many are exposed to potentially disturbing traffic related noise at night....
In 1992, 1998, and 2006, questionnaires were sent to stratified samples of residents aged 18-75 years living near petrochemical industries (n = 600-800 people on each occasion) and in a control area (n = 200-1,000). The aims were to estimate the long-term prevalence and change over time of annoyance caused by industrial odour, industrial noise, and...
Internationally accepted exposure-response relationships show that railway noise causes less annoyance than road traffic and aircraft noise. Railway transport, both passenger and freight transport, is increasing, and new railway lines are planned for environmental reasons. The combination of more frequent railway traffic and faster and heavier trai...
There is growing evidence that having access to a quiet side of a dwelling reduces the harmful effects of road traffic noise on health and wellbeing. One measure to create a quiet side in existing noise-exposed residential areas is to erect shielding buildings that fill existing gaps through which road traffic noise penetrates. Within the EU-financ...
In the Nordic countries, a receiver height of 2 m has often been used when calculating noise levels over large areas for socio-acoustic surveys, but within the EU 4 m is used. Here, results are presented for railway noise calculations at both heights in 1459 points across several areas in Sweden. The average difference in equivalent level is 2.5 dB...
This study is part of the Swedish research program TVANE, where a number of questionnaire surveys have been performed. A comparison
between three areas demonstrates that the reported annoyance is higher where the traffic intensity is higher even if the equivalent
noise level is the same. The traffic intensity varies with a factor of 7 between the a...
The present paper explores the influence of the physical environmental qualities of "quiet". courtyards (degree of naturalness and utilization) on residents' noise responses. A questionnaire study was conducted in urban residential areas with road-traffic noise exposure between L(Aeq,24h) 58 to 68 dB at the most exposed façade. The dwellings had "q...
The aim was to develop and evaluate a seven-point category scale, called the Environmental Annoyance Scale (EAS), with semantic descriptors and ratio-scale properties. Six studies were conducted that involved ratings of perceived magnitude of descriptors, selection of seven descriptors with semantic coherency, and ratings of various environmental i...
A growing body of literature indicates that contact with nature influence people's health and psychological well-being both directly and by moderating processes. A questionnaire study was conducted in urban residential settings with high road-traffic noise exposure (LAeq, 24 h = 60–68 dB). Out of 500 residents, 367 lived in dwellings with access to...
Socio–acoustic surveys were carried out as part of the Soundscape Support to Health research programme to assess the health effects of various soundscapes in residential areas. The study was designed to test whether having access to a quiet side of one's dwelling enhances opportunities for relaxation and reduces noise annoyance and other adverse he...
Increasing evidence shows that certain personality traits, such as negative affectivity (trait NA), are strongly associated with the reporting of symptoms. The role of personality in sick building syndrome (SBS) symptom reporting is therefore explored with the aid of a questionnaire completed by occupants living in apartments with indoor climate pr...
We investigated a recently introduced office automation system at Swedish Telecom. In a first study, where 275 users answered an inventory, the users indicated that they found the system useful, but that they would like better user support. Paper and on-line support were most often used at the syntax level, but were not regarded to be very satisfac...
