Välisõhus leviva müra normtasemed ja mürataseme mõõtmise, mä Art. 12Müra hinnatud taseme määramine

(1) Müra hinnatud taseme määramiseks teatud ajavahemikus kasutatakse asjakohase programmiga modelleerimist või käesolevas paragrahvis esitatud arvutusmetoodikaid.

(2) Müra hinnatud tase L Ar,ti teatud ajavahemikus t i arvutatakse järgmise valemiga:

L Ar,ti = L Aeq,ti + K 1i + K 2i , dBA, kus L Aeq,ti on teatud ajavahemikus mõõdetud A-korrigeeritud ekvivalentne müratase, dB; K 1i on parandustegur müra tonaalsusele, K 1i = +5 dBA; K 2i on parandustegur impulssmürale, K 2i = +5 dBA.

(3) Tonaalse ja impulssmüra parandustegurid valitakse standardite ISO 1996-1, ISO 1996-2 või muu samaväärse standardi alusel. Korraga rakendatakse üht parandustegurit.

(4) Müra hinnatud tase L Ar,LT teatud ajavahemikus, mis sisaldab seeriamõõtmise ajavahemikke t i , arvutatakse järgmise valemiga: iVBORw0KGgoAAAANSUhEUgAAASQAAABRCAMAAABMvysYAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJ bWFnZVJlYWR5ccllPAAAA2RpVFh0WE1MOmNvbS5hZG9iZS54bXAAAAAAADw/eHBhY2tldCBiZWdp bj0i77u/IiBpZD0iVzVNME1wQ2VoaUh6cmVTek5UY3prYzlkIj8+IDx4OnhtcG1ldGEgeG1sbnM6 eD0iYWRvYmU6bnM6bWV0YS8iIHg6eG1wdGs9IkFkb2JlIFhNUCBDb3JlIDUuMC1jMDYwIDYxLjEz NDc3NywgMjAxMC8wMi8xMi0xNzozMjowMCAgICAgICAgIj4gPHJkZjpSREYgeG1sbnM6cmRmPSJo dHRwOi8vd3d3LnczLm9yZy8xOTk5LzAyLzIyLXJkZi1zeW50YXgtbnMjIj4gPHJkZjpEZXNjcmlw dGlvbiByZGY6YWJvdXQ9IiIgeG1sbnM6eG1wTU09Imh0dHA6Ly9ucy5hZG9iZS5jb20veGFwLzEu MC9tbS8iIHhtbG5zOnN0UmVmPSJodHRwOi8vbnMuYWRvYmUuY29tL3hhcC8xLjAvc1R5cGUvUmVz b3VyY2VSZWYjIiB4bWxuczp4bXA9Imh0dHA6Ly9ucy5hZG9iZS5jb20veGFwLzEuMC8iIHhtcE1N Ok9yaWdpbmFsRG9jdW1lbnRJRD0ieG1wLmRpZDpCQTI0RkU3NThBQzZFNjExOTgxMzhDMEM1NjUx MzE1NiIgeG1wTU06RG9jdW1lbnRJRD0ieG1wLmRpZDo0NkQ2QjgwNEM2QTExMUU2QjhBOEMwNjFG Mzc5OTRBRCIgeG1wTU06SW5zdGFuY2VJRD0ieG1wLmlpZDo0NkQ2QjgwM0M2QTExMUU2QjhBOEMw NjFGMzc5OTRBRCIgeG1wOkNyZWF0b3JUb29sPSJBZG9iZSBQaG90b3Nob3AgQ1M1IFdpbmRvd3Mi PiA8eG1wTU06RGVyaXZlZEZyb20gc3RSZWY6aW5zdGFuY2VJRD0ieG1wLmlpZDpCQTI0RkU3NThB QzZFNjExOTgxMzhDMEM1NjUxMzE1NiIgc3RSZWY6ZG9jdW1lbnRJRD0ieG1wLmRpZDpCQTI0RkU3 NThBQzZFNjExOTgxMzhDMEM1NjUxMzE1NiIvPiA8L3JkZjpEZXNjcmlwdGlvbj4gPC9yZGY6UkRG PiA8L3g6eG1wbWV0YT4gPD94cGFja2V0IGVuZD0iciI/PgP2D8gAAACQUExURSAgILz//yAgdEyZ 3v//3plMIN6ZTP+8dHS8/5ne/97//7x0IP//vCBMmXQgIP/emSB0vCAgTEwgIHQgTEwgTEwgdLz/ vExMmZlMdJlMTLyZmUxMILx0THRMmXS83nQgdN6Zmd7/vJm8/0xMTCB0dCBMdHR0IEx0vLx0dJl0 mUyZmby8vHRMTEx0dN6ZdP///2tiQv4AAAUbSURBVHja7JzpeqMgFIZpMYDBRptOO/u+r97/3Q2H TUTcJjGpk8OPNJM4Ii9n+TjwhNTYRhtBBAgJISEkhISQEBJCelyt2JGqrhm5zRFSf+Pk+qrONgIt aaCxHztaZ8+uENJAe5XLm235dHvJkLINIUMBp3h7VT7JebWYoaruCX30kK4HPan8qi6hcsmQxFYP iakBsM+/coQ09LUAGXCzRUhDA4CvZVUjpDOLjHVBKnYUIQ1DAjWAkIYh8ducI6Rxd0NI8yBxkmqL BPn1QoIAVSX1AEKiQaYjRJxELqw5JvHuwpchpDhwS0Ki5QhHSDGkU+mmdUuAcn+S0vbKdRJbKOmv F5KuUUZUZFcHDA+3iWImfqmbjmJeexUgoQMGmuJS7Crnqea+5ZO8/s8hpXTAwK2oVwkvtjYTTlAN syGpGSBHqXA1VQ8otYtmzDMFIuvogN4O9CfcMbWQJtTrWpCU7ar+rOuHE0RaU1cdxT589pbqYWVA aSakHh2Q6qDYiQ6kwQqVpAlLyjYwKeaxyn1DqQ3pCBsTQdWj3NOwSF3u5y41kjog2YGxJF950W+a kNTqOXue97lbCEnBpylI7EjKxI1B368hMR8SuGjqkm4H2QZODbjpMJAgJOnt3+z5S6owXj/s1CeQ D8y7EUgsDUkeSZi4MZj7SYfeQGLG48W0RWtaByQ6UEQgeBd3uZ9tCEkcRi0Fo/U7Bebh9dZ+5HY8 GxIA7/ZlaElJd3Mp9FiQ/IyIABL8q9ybKZ8AKa0DUh0YnACJG8llZqPSQJj6U95b46HuJYRU7uFK 0kBiQb+t7DZ3tSSbkliYhgYgGYO2Jjul/KHCkpg6C/BEInUH/XjczYwIrmNhCvDuFiW3ENJR4vY/ QIoqkLEpJVRAP6SULQoTpHQ+45WytfKDevnZgmS6CWMSD+adpEMSj2K4lfh6VsiYEm6HDNaKSTAi 59cTLCl9SU8HPTLiZgunwYwF8Up/oF7ECKR04LZX6ARZ3H2MOjb5VJks6P+7fIq7ufjZzm6S+Fg8 AVLaSno6mNC+XaXFZAJSoBpJJGNNeJNvNuAaRHhJZST+nxzybPZ9O8mS9N8mHRhLovMkQDWjgwOq AOZRHKp+S+JGuVbWKCkcofr99P1rA0RWwSJpogTINopw4wzwceu/j0LqOy3R08EhpRJ9S0nCmKRP IpioGeg2Yg81FW+15rDW114t6Tg4tpZwVQ947zlAPKO2GzOuUUgyNf7eDg6rJ4FieAOR163d9Ngj SHFmr1pAvMTnh6lyc0tL30OyxQ14PDEakE5adJP6QROQjEqtWrV3L/HZYceFWFjECLa5g7V8IHCq +syQrJmQni8AoQUCycxJfL1GOlhCWdkaQPqkY2GrSlbszl++tZqTJFz+Vkt76oK1guQlviQHugAP dFYDiVHt/Dw0U7mqjYDFTnZ6SEro6dzKqrp3Y+DiNwKUrYL2CPXBKQLSuiDBeXYZKPmUOljmJNyK IDFdphCumKFViOgs5i8ckjSriyZuJwLSMqJpPZCMm8nrL9RbTUeNqYX8ZUMybtZsObmFQbstogjW A4nZHSCHgRGEFENye5DS+ljakPA44NkaQkJICKlbtlrmyOR/ZUn+yBFCCgoP0bP7I0cIKdTXopEC ZoMHIXXc6z7+AiF143Zn7XbBkPpWG7pwvLi7reJ3AQboUR6t+dk5f9Xlcf4Mh4y2t/lii7cVQ3pk DSEhJISEkBASQkJICAkbQvrn9leAAQBrdqy9CZ6EHgAAAABJRU5ErkJggg==

(9) Müra hinnatud tase öise ajavahemiku vältel arvutatakse järgmise valemiga:

L n = L r,T3 ,

(10) Müra hinnatud tase öise kõige mürarikkama tunni ajal arvutatakse järgmise valemiga:

L n,1h = L r,T4 ,

(11) Kui müra hinnatud tase öise mürarikkaima tunni vältel on enam kui 4 dBA võrra suurem kui hinnatud tase kogu öise ajavahemiku vältel, võetakse öise müra hindamisel aluseks hinnatud tase kõige mürarikkama tunni vältel.
