THE EFFECTS OF NOISE ON OFFICE OCCUPANTS AND ITS SOLUTION. ... As a reference for the discussion below, typical office levels run from ambient levels of 40 DB(A) to 70 dB(A) near conversations. The “A” represents the frequency distribution of the sound as modified by the hearing mechanism of people. The symbol with be omitted in the text.

Ambient noise . SHALL NOT. exceed 60 decibels (db) in any tenant spaces, measured from the center of the space at a height of 60 inches. Tenant space is defined as the footprint of space the tenant is leasing. A shunted circuit is necessary if any device installed in the tenant space generate any ambient noise (Example TVs, Jukebox and Stereo).

Table 2.6-3, Existing Ambient Noise Levels at Noise Monitoring Locations, presents the results of the noise modeling of existing traffic noise levels, at the noise measurement locations. For purposes of this EIR, Appendix G of the CEQA Guidelines (14 CCR 15000 et seq.) will apply to the direct, indirect, and cumulative impact analyses.

TNM model validation will be acceptable when the Leq(h) modeled noise levels are within ± 3.0 dB(A), preferably ±1.7 dB(A), of the ambient data Leq(h) for all noise monitoring receptor locations for which traffic was dominant. All TNM validation models must be approved by NCDOT prior to predicting existing and future noise levels.

Noise, Radiation, and Other Exposures for Construction. These regulations are not designed to cover nuisance noise exposure (e.g. ambient noise, road traffic, etc.). They are designed to protect against hearing loss and apply to situations in which noise levels equal or exceed 85 . dBA. as an . 8-hour time-weighted-average. The OSHA

Nighttime: 65 dB. 2. In the event the existing local ambient noise level exceeds the maximum allowable receiving noise level (dB), the receiving noise level maximum for construction operations shall be adjusted as follows: a. Residential receiving area: Maximum 3 additional dB above the local ambient as measured at property line. b.

The ambient noise levels used to calculate the boundaries are derived from Recommendation 372, characteristics and applications of atmospheric radio noise data. The Loran-C field strength, measured at the boundary of that coverage area, then represents the minimum expected. For example, if the expected noise level is 55 dB(µV/m), a Loran-C ...
