Chamber Investigation and Evaluation of Acoustic Properties of Materials/Kameriniai Medžiagų Akustinių Savybių Tyrimai Ir Vertinimas/Камерные Исследования И Оценка Акустических Свойств Материалов

Abstract: Traffic‐generated noise accounts for 60–80% of the noise prevailing in towns. With the aim of reducing the impact of noise on humans, measures and methods of fighting noise in towns and residential areas should be developed. In the majority of cases, noise suppression walls (barriers) are one of the most suitable means in tows to reduce the dispersion of noise to residential territories. Acoustic properties of materials to be used for noise walls were investigated and, on the basis of the obtained findings, th… Show more

“…Triukšmo lygis darbo vietoje ar namų aplinkoje yra vienas pagrindinių veiksnių, lemiančių komforto rodiklį, todėl triukšmo procesams nagrinėti skiriama vis daugiau dėmesio (Grubliauskas, Butkus 2009). …”

“…With increasing frequency, the insulation of a noise barrier also increases (21). Insulation is worsened by resonant and critical frequencies (8). Resonant frequencies are overlapping frequencies of sound waves and barrier's own vibrations.…”

“…-reducing noise at the source -from machines, engines, tyres and surface; -reducing speeds and traffic volume as well using special equipment (Baltrėnas et al 2007b;Vaiškūnaitė et al 2009;Vaišis, Januševičius 2009); -limiting the transmission of noise by placing sound barriers between the source and people affected (Baltrėnas et al 2007a;Vaišis, Januševičius 2009); -reducing noise at the reception point, such as noise insulation of buildings (Grubliauskas, Butkus 2009). To implement the diversity of these methods, the policy decisions are in use and include the development of emission standards for individual sources, immission standards based on noise quality criteria, land use planning, infrastructure measures, economic instruments, environmental noise researches, operational procedures as well as education and information actions (Paslawski 2009).…”
