New parameters for the advanced search of the database

The following acoustic indices have been added to the advanced search tool of the database:

• R_w: Weighted sound reduction index [dB].
• D_n,e,w: Weighted element-normalized level difference [dB].
• D_n,f,w: Weighted normalized flanking level difference [dB].
• L_n,w: Weighted normalized impact sound pressure level [dB].
• ΔL_w: Weighted reduction in impact sound pressure level [dB].
• ΔR_w: Weighted sound reduction index improvement [dB].
• L_n,f,w: Weighted normalized flanking impact sound pressure level difference [dB].
• L_na: Normalized sound pressure level, A-Weighted [dB(A)].
• L_sc: Characteristic sound pressure level (structure-borne sound) [dB].
• L_wa: Sound power level, A-Weighted [dB(A)].
• α_w: Weighted sound absorption coefficient according to EN ISO 11654.
• L_iA: Rain impact noise intensity level, A-Weighted [dB(A)].
  

This way, it is now possible to filter elements that appear in the access interface of the database in accordance with the requirements of the project.
