Acoustic Wave Phenomena Research

Ensuring acoustic comfort in educational environments is crucial for both pedagogical efficiency and user health. This study examines the acoustic performance of a newly constructed university research center in Türkiye, in line with the criteria set out in the “Regulation on the Protection of Buildings Against Noise.…

Background and aims This study aims to investigate the role of reinforcement type in determining the sound absorption performance of wood-based sandwich panels (WBPS) reinforced with basalt fiber fabric, glass fiber fabric, and jute fabric, using a single-component polyurethane adhesive (PUR-D4). Methods As wood-based…

Termoakustik ses enerjisinin ısı enerjisine dönüşümü veya bunun tersi ile ilgilenen multidisipliner bir bilim dalıdır. Termoakustik teknoloji, sürdürülebilir enerji teknolojilerinin geliştirilmesine yönelik güçlü bir potansiyele sahip olan yeni ve gelişmekte olan bir teknolojidir. İmalatı basit olmasına rağmen, termoa…

Automated Machine Learning (AutoML) frameworks are efficient tools for predictive model applications. Several machine learning algorithms can integrate them. This study presents a comprehensive evaluation of four AutoML frameworks that are FLAML, H2O, TPOT, and PyCaret to predict the fundamental frequency of perforate…

Abstract This study numerically investigates high-speed impacts on composite radomes against bird and drone strikes. With the rising UAV activity near flight paths, traditional bird-strike numerical models no longer capture all foreign object damage risks. Simulations were conducted on sandwich and laminated radomes u…

Pentamode metamaterials, characterized by their near-zero shear modulus and high bulk modulus, have attracted solid interest due to their unique ability to mimic fluid-like behaviour. Pentamode metamaterials have driven by improvements in computational design, material selection and advanced manufacturing techniques,…

The Mansour nay is a woodwind instrument made from a single piece of giant reed (Arundo donax L.). Because the body is natural and cannot be modified after construction, geometric variability across specimens is inevitable and directly affects the pitch frequencies produced by the instrument. Identifying which geometr…

This study presents the development of hybrid composites using waste krajood fibers and isocyanate adhesive for sustainable building applications. The influence of fiber size (short, long, and mixed) and fiber-to-adhesive ratios (90/10, 85/15, and 80/20 wt%) on mechanical, physical, thermal, surface morphology, water…

Camiler, birçok insanın dini faaliyetlerini birlikte gerçekleştirdiği yerlerdir. Şehir ölçeğinde hizmet veren yüksek kapasiteli camilerin yanında mahalle ve köy ölçeğinde hizmet veren düşük kapasiteli camilerin de dini hayatta önemli yerleri bulunmaktadır. Bu camilerden biri de Doğu Karadeniz Bölgesi'ndeki geleneksel…

Acoustic emission (AE) characteristics of surface-to-surface furniture joints connected using adhesive only, staples only, and a combination of adhesive and staples were investigated under lateral load. AE cumulative counts-time curves of the evaluated joints can be divided into three distinct stages based on AE count…
