Sound insulation (building acoustics) – sound energy losses propagating through the building structures between the sound source and the listener.
Sound insulation can be divided into two groups:
Isolation of airborne sound and isolation of impact sound insulation.
The ability of structures to isolate sound (sound that is unwanted is called noise) is based on the strict laws of physics (objectively). But the consequences of sound insulation, i.e. how much noise has passed through the partitions is assessed more subjectively. In addition, sound insulation is measured in logarithmic units in dB (decibels), where the user-normal arithmetic actions “1 + 1 = 2” do not apply. As a result, sound insulation and its evaluation become very complicated, knowledge and experience in this field are particularly important. The quality of the contract work and the assessment of the sound propagation of adjacent roads play a very important role in the performance of sound insulation.
Measurements and evaluations of sound insulation properties of building structures are also performed. Tasks for architects, constructors, designers are prepared in accordance with the applicable requirements and recommendations. We help the client to create a sound insulation task and explain the requirements of the task. We calculate and simulate the sound insulation properties and sound propagation through structures in a building. We prepare projects for the sound insulation part, perform evaluation and audit of selected solutions. We supervise contract work, inspect objects and consult.
Lithuania national symphonic orchestra (Vilnius congress hall) are implementing renovation and modernization of a building at Vilniaus str. 6, Vilnius. The goal of this project is to complete reconstruction works at Vilnius congress hall adapting the space purposely for symphonic orchestra.
A new universal hall with exclusive interior design solutions is being prepared at the House of Polish Culture in Vilnius. The big highlight of the hall will be two-color lamellas.
Several acoustically sensitive spaces are being designed at Lithuanian National Drama Theater: the new hall of the musical theater, the sound recording studio, the rehearsal hall and the acting hall.
“Akustika plius” came to the Lithuanian National Drama Theater with the aim of achieving acoustic comfort while minimizing damage to the visual concept of the spaces.
1938 – 1940 Designed by architect Nikolai Mačiulskis, the Romuva cinema is classified as an Art Deco, functionalist / modernist architectural style. The project of the main cinema hall of the acoustic interior aims to maintain the direction of modernism by preserving and emphasizing the most valuable existing architectural and structural elements.
Akustika plus designed the sound insulation, interior and acoustics of the rehearsal hall of the Lithuanian National Opera and Ballet Theatre.
The Dropaudio sound recording studio is equipped according to prepared architectural acoustics, acoustic interior, noise control projects and after the supervision of the contract works.
Klaipėda national musical theatre has a few acoustically sensitive spaces that are being designed by our company: musical theatre main hall, small multifunctional hall, sound recording studio, rehearsal hall for orchestra, rehearsal hall for choir and other instruments.
National Mikalojus Konstantinas-Čiurlionis art school main hall acoustic interior project was done by our company.
