would be compared to the values contained in the Noise Exposure Guidelines. If these noise levels would exceed the marginally acceptable levels, a significant impact would occur unless the building design as proposed provides a composite building attenuation that would be sufficient to reduce these levels to an acceptable interior noise level. These values are shown in Table 19-3. The applicant should demonstrate that sufficient attenuation is provided in the form of composite building attenu- ation calculations based upon the Outdoor Indoor Transmission Class (OITC) values of individual ma- jor window/wall/ventilation components, unless a federal funding source, as defined in Subsection 723 of this chapter, requires usage of a different single number rating, such as the Sound Transmis- sion Class (STC) rating, to calculate the noise levels and attenuation values. 421.2. Aircraft Noise If the proposed project would create an aircraft facility (heliport or airport), cause a change in flight paths or flight frequency at an aircraft facility, or be subject to aircraft noise, the impact criteria dis- cussed in Sections 410 and 420 apply. If these levels in dB(A) Ldn(y) exceed the marginally acceptable level, a significant impact would occur, unless the building design as proposed provides a composite building attenuation that would be sufficient to reduce these levels to an acceptable interior noise level. In the case of significantly impacted buildings, design measures should be implemented that achieve the levels of composite building attenuation provided in Table 19-3. The applicant should demonstrate that sufficient attenuation is provided in the form of composite building attenuation calculations based upon the OITC values of individual major window/wall/ventilation components, unless a federal funding source, as defined in Subsection 723 of this chapter, requires usage of a dif- ferent single number rating, such as the STC rating, to calculate the noise levels and attenuation val- ues. 421.3. Train Noise If the proposed project would create a rail facility, cause a change in frequency of trains along the rail facility, or be subject to rail noise, the impact criteria discussed in Sections 410 and 420 apply. If these levels in dB(A) Ldn(1) exceed the marginally acceptable level, a significant impact would occur, unless the building design as proposed provides a composite building attenuation that would be suf- ficient to reduce these levels to an acceptable interior noise level. In the case of significantly impact- ed buildings, design measures should be implemented that achieve the levels of composite building attenuation provided in Table 19-3. The applicant should demonstrate that sufficient attenuation is provided in the form of composite building attenuation calculations based upon the OITC values of individual major window/wall/ventilation components, unless a federal funding source, as defined in Subsection 723 of this chapter, requires usage of a different single number rating, such as the STC rating, to calculate the noise levels and attenuation values. Table 19-3 Required Attenuation Values To Achieve Acceptable Interior Noise Levels Marginally Unacceptable Clearly Unacceptable Noise level with proposed project 70<L10≤73 73<L10≤76 76<L10≤78 78<L10≤80 80<L10 AttenuationA (I) 28 dB(A) (II) 31 dB(A) (III) 33 dB(A) (IV) 35 dB(A) 36 + (L10 - 80)B dB(A) Note: A The above composite window-wall attenuation values are for residential dwellings and community facility development. Commercial office spaces and meeting rooms would be 5 dB(A) less in each category. All of the above categories require a closed window situation and hence an alternate means of ventilation. B Required attenuation values increase by 1 dB(A) increments for L10 values greater than 80 dBA.
