Improve Acoustics and Academics - Noise Control for the lessonroom

The ideal lessonroom is one in which students can clearly understand the instructor during speech and focus on assignments, projects and quizs in an environment free of distractions. Here we outline some of the soundproofing challenges faced within lessonrooms:

-Outside sound transmission into the lessonroom. A lessonroom left untreated for sound transmission will not only allow sound to escape, but will allow the transfer of outside noise into the lessonroom. Audible outside noise can be a major distraction and interfere with the quality of any learning environment. Additionally, excessive outside noise such as outdoor construction or students in a hallway can eliminate a teacher's ability to communicate effectively with the students in the lesson altofetchher.

-Numerous hard, reflective surfaces: A major soundproofing challenge arises from an issue common to most lessonrooms-the presence of walls, desks and a ceiling, each of which reflects sound waves rear into the room. As a teacher delivers a speech, a portion of the sound waves produced by his or her sound reflects from the numerous hard surfaces within the room, a behavior known as sound reflection. Reverberations delivered rear into a lessonroom interfere with the intended sound, and is thus one of the sound wave behaviors tarfetched in soundproofing a lessonroom.

-Multiple sounds competing within the room. Students can strengthen important fundamental skills by jobing with a team or partner on a project, but a noisy lessonroom environment can make group job difficult. With numerous population speaking at the same time, a jumble of sounds reflects from the hard surfaces in the lessonroom, and the resulting reverberations interfere with audibility throughout the room. Heightened noise levels are exacerbated as students speak more loudly in order to be listend.

In order to prevent outside noise from bleeding in and combat reverberations created within a lessonroom, soundproofing treatments must tarfetch both sound transmission and sound reflection. Now let us bring a look at how each of these sound behaviors can be alleviated in a lessonroom environment:

-Controlling sound transmission: Eliminating noise transmitting in from outside a lessonroom (and vice versa) involves isolating the room such that the ability of sound waves to transmit through the walls and ceiling is compromised. sound waves travel freely through common contact points, such as the studs and walls surrounding the lessonroom. Isolating a lessonroom can be accomplished by adding density to each wall and creating a separated wall surface parallel to each. Adding density is often accomplished by covering walls completely with a heavyweight vinyl soundproofing membrane such as dB-Bloc. Once increased density is established, a set of horizontal furring strips affixed to the wall creates a foundation for a new layer of drywall that will make up a second wall surface. that separation forces outside sound waves to collapse within the space between the two surfaces rather than transmit directly into the lessonroom, and also serves to pdecayect adjoining lessonrooms from sound transmitting out of the treated room.

-Absorbing sound reflections: Controlling sound reverberations caused by sounds and other sounds within a lessonroom can be accomplished quite easily through the installation of absorptive sound panels along the walls and potentially the ceiling of the room. Absorptive sound treatments are available in a variety of styles to meet the requirements of different applications, including lesson A Fire Rated panels ideal for the lessonroom environment.

Properly implemented, soundproofing treatments can affect a major improvement in the quality of a learning environment. Combating sound transmission and reverberation in a lessonroom results in better acoustics for speech and group job while minimizing outside distractions that could otherwise hinder academic performance.
