Abstract

In this article, the changes of pressure and speed on the various media surfaces, created by the sound waves are studied. Sound waves are used in the study due to their similarity to ultrasound waves. As the wave model, the Gaussian pulse wave pattern has been preferred. While inanimate surfaces such as air, water, metal, s-oil, polyethylene are used as ambient surfaces, and muscle and connective tissue surfaces are used as the living tissue in analyses. The pressure effects of acoustic waves on the selected media surfaces are investigated using the finite difference time domain (FDTD) method. In the study of the Gaussian sound wave, the propagation value increases as the number of iterations rises. In polyethylene layers, the effect of the pressure created by the sound is low (Pplastic = 39,5 µPa and Vplastic = 13,17 µm / sec). The study implemented on living tissues as a connective and muscle tissue depicts that a sound wave creates similar pressure (Pconnective =1,295 Pa, Pmuscle=1,282 Pa) and velocity (Vconnective=0,63 µm/sec, Vmuscle= 0,58 µm/sec) values in both tissues.

Abstract

Bu çalışmada ses dalgalarının farklı ortam yüzeylerinde meydana getirdiği basınç ve hız değişimleri ele alınmıştır. Ultrason dalgalarına benzerliği nedeniyle çalışmada ses dalgaları kullanılmıştır. Dalga modeli olarak, gauss nabız dalga modeli kullanılmıştır. Ortam yüzeyleri olarak hava, su, metal, s-oil, polietilen gibi cansız yüzeyler, doku türleri da olarak bağ doku ve kas dokusu yüzeyleri analizlerde kullanılmıştır. Seçilen bu ortam yüzeylerinde, akustik dalgalarının oluşturduğu basınç etkileri, zamanda sonlu farklar (FDTD) metodu kullanılarak incelenmiştir. Örneklenen gauss ses dalgasının analizinde, iterasyon sayısı arttıkça yayılım değeri de artmaktadır. Polietilen yapılı katmanlarda ise sesin oluşturduğu basıncın etkisinin düşük olduğu (Pplastik=39,5 µPa ve Vplastik=13,17 µm/sn ) tespit edilmiştir. Canlı dokulardan bağ dokusu ve kas dokusu üzerinde yapılan incelemede ise bir ses dalgasının bu iki doku üzerinde benzer basınç (Pbağ=1,295 Pa, Pkas=1,282 Pa) ve hız (Vbağ=0,63 µm/sn, Vkas= 0,58 µm/sn) değerleri oluşturduğu gözlenmektedir.
