Summary This standard specifies the environmental noise is used to describe the community 's basic parameters and evaluation methods. Details the steps in assessing environmental noise, and gives the predicted long-term exposure to a variety of people to the potential environmental noise annoyance response guidelines. May be separate noise sources, it can be a combination of a variety of sound sources. Prediction method is used only annoyance reactions people live in the area and long-term land use situation. People with the same sound level noise sources reaction with a big difference. This section describes the different characteristics of the noise correction. The term "Review sound level " is used to describe the addition of one or more modified or measurement of the actual noise prediction. Sound level can be estimated based on the evaluation long-term annoyance reactions. Signal to noise alone or in combination with means for evaluation. When the competent authorities consider necessary, may consider their impulsive, tone and frequency characteristics, and the different characteristics of road traffic noise and other forms of traffic noise (such as aircraft noise) and industrial noise. This section does not specify the ambient noise limits.

It also specifies methods to assess environmental noise and gives guidance on predicting the potential annoyance response of a community to long-term exposure from various types of environmental noises. The sound sources can be separate or in various combinations. Application of the method to predict annoyance response is limited to areas where people reside and to related long-term land uses. Community response to noise can vary differently among sound sources that are observed to have the same acoustic levels. This document describes adjustments for sounds that have different characteristics. The term “rating level” is used to describe physical sound predictions or measurements to which one or more adjustments have been added. On the basis of these rating levels, the long-term community response can be estimated. The sounds are assessed either singly or in combination, allowing for consideration, when deemed necessary by responsible authorities, of the special characteristics of their impulsiveness, tonality, and low-frequency content, and for the different characteristics of road- traffic noise, other forms of transportation noise (such as aircraft noise), and industrial noise. This document does not specify limits for environmental noise. NOTE 1: In acoustics, several different physical measures describing sound can have their level expressed in decibels (e.g. sound pressure, maximum sound pressure, and equivalent continuous sound pressure). The levels corresponding to these physical measures normally will differ for the same sound. This often leads to confusion. Therefore, it is necessary to specify the underlying physical quantity (e.g. sound pressure level, maximum sound pressure level, and equivalent continuous sound pressure level). NOTE 2: In this document, quantities are expressed as levels in decibels. However, some countries validly express the underlying physical quantity, such as maximum sound pressure, in pascal or sound exposure in pascal-squared seconds. NOTE 3: ISO 1996-2 deals with the determination of sound pressure levels. Event duration shall be specified relative to some characteristic of the sound, such as the number of times that some fixed level was exceeded. EXAMPLE: The duration of a sound event can be defined as the total time that the sound pressure level is within 10 dB of its maximum sound pressure level. NOTE: While the sound exposure level combines sound level and duration, the concept of event duration can be useful to differentiate events. For example, an aircraft pass-by can have a duration of 10 s to 20 s, while the duration of a gunshot is less than 1 s. 5.2 Repetitive Single Events Repetitive single-event environmental sounds are typically re-occurrences of single-event sounds. For example, aircraft noise, railway noise, or road-traffic noise with a low traffic volume, can be considered as the sum of the sound from multiple individual events. Also, the sound from gunfire is the sum of the sound from multiple individual gunshot sounds. In this document, the description of all repetitive single-event sound sources utilizes the sound exposure levels of the single-event sounds and the corresponding number of events to determine the rating equivalent continuous sound pressure levels. 5.3 Continuous Sound Transformers, fans, and cooling towers are examples of continuous sound sources. The sound pressure level of the sound from a continuous sound source can be constant, fluctuating, or slowly varying over a time interval. Continuous sound is preferably described by the A- weighted equivalent continuous sound pressure level over a specified time interval. For fluctuating and intermittent sounds, the A-weighted maximum sound pressure level with a specified time weighting can also be used. NOTE: Depending on the situation, road-traffic noise can be classified as a continuous source or as the sum of many repetitive single-event sounds. 6 Noise Annoyance 6.1 Descriptors for Community Noise This document provides guidance on the assessment of environmental noise from individual sources or any combination of sources. Responsible authorities may decide what sources, if any, are to be combined, and what adjustments, if any, are to be applied. If the sound has special characteristics, then the rating equivalent continuous sound pressure level shall be the primary measure used to describe the sound. Other measures such as the maximum sound pressure level, the (adjusted) sound exposure level, or the peak sound pressure level also may be specified. Research has shown that the frequency weighting A, alone, is not sufficient to assess sounds characterized by tonality, impulsiveness, or strong low-frequency content. To estimate the long- term annoyance response of a community to sounds with some of these special characteristics, ......
