The previous versions of this document and the documents it replaces are as follows. First published in.1993 as GB 14227-1993; - During the first revision in.2006, the contents of GB/T 14228-1993 “Measurement of noise on subway station platforms” were incorporated; This is the second revision. - Urban rail transit station Platform acoustic requirements and measurement methods1 ScopeThis document specifies the acoustic requirements and measurement report contents for trains entering and leaving urban rail transit station platforms. Measurement methods and reverberation time measurement methods. This document is applicable to new and renovated buildings with a maximum design speed of no more than 160 km/h, supported by steel wheels and rails, and powered by electricity. Design, measurement and evaluation of the acoustic environment of stations and platforms in urban rail transit systems and expansion projects; The measurement of the learning environment shall be carried out in accordance with this reference.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies. in this document.

Note 1.The equivalent continuous A-weighted sound pressure level is referred to as “equivalent sound level”. Note 2.The expression of equivalent continuous A-weighted sound pressure level is shown in formula (1). LAeq;T = 10lg 2666664 1t2%00 t1 w t2 t1 p2A (t) p20 dt 3777775 (1) Where. LAeq;T ─ equivalent continuous A-weighted sound pressure level, in decibels [dB(A)]; t2%00 t1 ─ specified time period, in seconds (s); pA (t) – A-weighted sound pressure, unit is Pascal (Pa); p0 - reference sound pressure, taken as 20 μPa. LpA Note 3.When A-weighted sound pressure is expressed as A-sound level, the expression for the equivalent continuous A-weighted sound pressure level is given by formula (2). LAeq;T = 10lg t2%00 t1 w t2 t1 10（LpA=10）dt (2) [Source.
