- Noise is an environmental problem that affects children both at school and home. This chapter summarizes the results on noise disturbances from the “Children’s environment and health survey” conducted in Stockholm County in year 2003. It was found that children were most disturbed by noise at school. Thirty per cent of all 8- and 12 year old children in Stockholm County were annoyed by noise at school, mainly noise from other children. Children in Stockholm County were exposed to more noise in their homes than children in other parts of Sweden. Almost 50 % of children in inner city Stockholm and 20 % in the rest of the County were living in apartments with windows facing a major road, railway or industry. Eighteen per cent of all 8- and 12-year olds were disturbed by noise in their homes. Slightly less than 6 % reports that noise disturbed school homework or speech communication, whereas 4 % reported difficulties in falling asleep due to noise in the home. Approximately three per cent of parents to all 4-, 8- and 12-year old children reported that their children have reduced hearing, and three per cent of 8- and 12-year old children reported that they have tinnitus. It is concluded that noise in dwellings and schools should be reduced in order to provide good and healthy sound environments for children. Furthermore, the sound environment should be considered already at the planning stage, in order to minimize indoor and outdoor noise exposure in future dwellings and schools.

- The difference in perceived noise annoyance caused by train and highway noise at the same averaged noise level, has led to the introduction of the ’railway bonus’. This bonus has found its way to the noise legislation in many countries, leading to more relaxed restrictions on time averaged noise levels, LAeq. With the introduction of high-speed trains and train-like transportation systems based on magnetic levitation, the question has risen whether the railway bonus can still be applied. The paper reports on an experiment that was conducted to answer this question. The experiment that was performed was different from previous efforts in many ways. Most importantly, the experiment was conducted in a realistic setting, a holiday cottage, and participants were asked to engage in light daily activities such as reading a magazine during the tests. Traffic noise was reproduced in an ecologically valid way, using outdoor loudspeakers. Every ten minutes the participants were asked to judge noise annoyance. At the beginning of the experiment and after about 1.5 hours the participants were also asked to rate a set of 7 master scaling sounds. After this experiment, a more conventional listening test was conducted using 45-s excerpts. The experiment was also unique in the way that 100 participants were selected to be representative for the Dutch population. The selection procedure involved careful screening based on a survey that was administered at the doorstep of 1500 persons’ homes.
