THE ANALYSIS OF SOUND TRANSMISSION LOSS ON LAMINATED GLASS
Spektra: Jurnal Fisika dan Aplikasinya, 2022 Laminated glass is one type of glass that is commonly used for sound insulation (walls or doors). Tests related to the ability of insulating glass in Indonesia are still sporadic. One of the places to do this test is the SNSU BSN Lab.
