Bu çalışmada, aynı geometrik boyutlara sahip ancak farklı malzemelerden üretilmiş yedi adet plakanın ses iletim performansları deneysel olarak incelenmiştir. Deney düzeneğinde, 15 W, 25 W ve 40 W gücünde üç farklı ses uyarıcısı (sound exciter) kullanılarak malzeme türünün ve uyarıcı gücünün ses iletimi üzerindeki etkileri değerlendirilmiştir. Farklı malzemelerin akustik davranışları karşılaştırılmış, endüstriyel uygulamalardaki kullanım uygunlukları irdelenmiş ve güç seviyesinin ses iletim karakteristiklerine olan katkısı detaylı şekilde analiz edilmiştir. Elde edilen deneysel bulgular, malzeme seçiminin ve uyarıcı gücünün ses iletim performansında belirleyici rol oynadığını göstermekte olup, akustik tasarım süreçleri için önemli veri sağlamaktadır. Çalışma sonucunda, üç ayrı ses uyarıcısı ile titreştirilerek elde edilen ses basınç seviyeleri karşılaştırılmış ve hem malzeme sertliği–sönüm oranının hem de uyarıcı güç/empedansının akustik yanıtı belirlediği görülmüştür.

In this study, the sound transmission performance of seven plates with identical geometric dimensions but manufactured from different materials was experimentally investigated. Three sound exciters with output powers of 15 W, 25 W, and 40 W were employed to evaluate the influence of material type and exciter power on sound transmission behavior. The acoustic responses of the materials were compared, their suitability for industrial applications was assessed, and the contribution of varying power levels to transmission characteristics was analyzed in detail. The experimental findings demonstrate that both material selection and exciter power play a critical role in sound transmission performance, providing valuable insights for acoustic design and engineering applications. As a result of the study, the sound pressure levels obtained by exciting the plates with three different actuators were compared, revealing that both material stiffness–damping characteristics and actuator power/impedance significantly influence the acoustic response.
