v anglickém jazyce The possible assessments of unprofessional exposures of low frequency noise Introduction: Along with technical development, the number of sources of low frequency noise increases in the human environment and the number of complaints from people exposed to noise from these sources increases as well. The statutory limit for non-professional exposure to low frequency noise has not yet been established (due to the limited amount of data on low frequency noise exposure risks) in the EU countries (USA) and no WHO recommendations have been issued in this area. For these reasons, the hygienic limit for municipal/non-professional exposure to low frequency noise was not specified in the Czech Republic. Objecticve: The present dissertation thesis was to investigate whether the short-term experimental exposure to low frequency noise with the tonic component induces significant changes in the circadian rhythm of cortisol and alpha-amylase in saliva in the experimental set of volunteers. Saliva is a biological material that allows low-invasiveness collection. The work was supposed to assess whether possible changes could be used as objective indicators of the presence of the stress response to the noise exposure. Material and metods: An experimental study was conducted on a set of 100...
