Triukšmo tyrimas VGTU specialiose laboratorijose

Abstract

Baigiamajame darbe nagrinėjamas Vilniaus Gedimino technikos universiteto specialiose laboratorijose esančių įrengimų skleidžiamas triukšmas bei jo atsiradimo dėsningumai. Garso lygiui išmatuoti buvo atlikti eksperimentiniai matavimai. Garso lygiai matuoti ir rezultatai įvertinti pagal higienos normoje HN 33–1:2003 pateiktus reikalavimus. Rezultatai pateikti grafiškai ir atlikta jų analizė. Baigiamajame darbe taip pat pateikta apibendrinta keliamos problematikos analizė, triukšmą mažinančių priemonių apžvalga ir analizė, pasiūlytos triukšmą mažinančios priemonės tiriamose laboratorijose. Išnagrinėjus ir nustačius triukšmo šaltinių keliamo garso lygį ir jo atsiradimo dėsningumus, pateikiamos baigiamojo magistro darbo išvados ir pasiūlymai. Darbą sudaro penkios dalys: įvadas, apžvalginė – metodinė dalis, tiriamoji dalis, išvados ir pasiūlymai, literatūros sąrašas.

Noise outspread originated from machines located in laboratories of Transport engineering and Construction engineering faculties of Vilnius Gediminas Technical University and its origination consistency is being investigated in this article. To evaluate the level of sound there was taken experimental measurements. The level of sound measuring and the measurement results evaluation have been made according to requirements prescribed in Lithuanian hygiene standart HN 33 – 1:2003. Investigation results have been presented graphically, their analysis has been made with drawn inferences. There is summarized arisen problem analysis represented in this graduation work. Moreover it is presented review and analysis of noise abatement means, suggested these means implementation possibilities into laboratories. After investigation of the level of sound produced from noise origin and after determination of its originating consistency, conclucions and suggestions have been represented in this final graduation work. This work consists of five parts: introduction, methodical – review part, research part, conclusions and suggestions, list of literature
