The levels which interfere with listening to a desired sound, such as speech or music, can be defined in terms of the level of interfering sound required to mask the desired sound. Such levels have been quantified for speech communication by directly measuring the interference with speech intelligibility as a function of the level of the intruding sound, relative to the level of the speech sounds.
The levels interfering with human activities which do not involve active listening have not been as well quantified relative to the level of a desired sound. These relationships are more complicated because interference caused by an intruding sound depends upon the background level and the state of the human auditor; e.g., the degree of concentration when endeavoring to accomplish a mental task, or the depth of sleep, etc. Fortunately, there is a wealth of survey data on community reaction to environmental noise which, although subject to some shortcomings when taken alone, can be used to supplement activity interference data to identify noise levels requisite to protect public health and welfare. Thus, the levels identified here primarily reflect results of research on community reaction and speech masking.
Identified Levels for Interference
The level identified for the protection of speech communication is an
Leq of 45 dB within the home in order to provide for 100%
intelligibility of speech sounds. Allowing for the 15 dB reduction in sound
level between outdoors and indoors (which is an average amount of sound
attenuation that assumes partly-open windows), this level becomes an outdoor
Leq of 60 dB for residential areas. For outdoor voice communication,
the outdoor Leq of 60 dB allows normal conversation at distances up
to 2 meters with 95% sentence intelligibility.
Although speech-interference has been identified as the primary interference of noise with human activities and is one of the primary reasons for adverse community reactions to noise and long-term annoyance, the 10 dB nighttime weighting (and, hence, the term Ldn) is applied to give adequate weight to all of the other adverse effects on activity interference. For the same reason, a 5 dB margin of safety/ is applied to the identified outdoor level. Therefore, the outdoor Ldn identified for residential areas is 5 5 dB. (See Appendix E for relationship of Leq to Ldn.)
The associated interior day-night sound level within a typical home which results from outdoors is 15 dB less, or 40 dB due to the attenuation of the structure. The expected indoor daytime level for a typical neighborhood which has an outdoor Ldn of 55 dB is approximately 40 dB, whereas the nighttime level is approximately 32 dB (see Figure A-7). This latter value is consistent with the limited available sleep criteria D-5. Additionally,
