Properly designed open space provides us with a friendly and dynamic workplace. In open space, we want to ease communication within our team and protect against unnecessary noise coming from other workplaces. Meanwhile, ill-adapted spaces cause unwanted interference. Therefore, we should limit the propagation of sound over long distances by way of using acoustic screens at desks and a suspended ceiling or islands for a minimum 30% of the area.

During meetings with clients, presentations or employee councils, you want everyone to hear clearly and be able to join in the discussion at any time. This is all too often impossible due to too excess noise reverberation. For example, this can be a result of the walls being glazed and additionally equipped with a board and a screen. These surfaces strongly reflect sound and increase noise reverberation. In order to improve the acoustics, make sure that the speech intelligibility is as good as possible and that the background noise level is lower than 35 dB.

High noise (up to 95 dB) in the Call Center is closely related to the nature of the work and high staff density. These factors cause fatigue and disruptions during phone calls. The worse the conditions, the more mistakes we make, our effectiveness decreases and the breaks between conversations become longer. To prevent this, we should use acoustic screens (at least 50 cm above the desk), which ensure greater comfort for the callers and their interlocutors.

Sometimes, we all perform tasks that require silence. Focus Room is the perfect place for work that requires concentration, or for meetings in small, 2-3 person groups. That's why we work to create the right atmosphere of intimacy and confidentiality. The surface of the walls should be covered with a minimum of 50% acoustic panels to ensure low reverberation time. In addition, the room should have a suitable construction, which guarantees wall insulation of a minimum R'A1 ≥ 40 dB.

The reception is the company’s showcase because it is the first impression that lasts. We should feel at ease and cozy on entrance to this area. Unfortunately, most of these halls are designed from hard materials that reflect sound such as glass, stone or wood. This can cause discomfort. Wall or ceiling acoustic panels for the reception should be interesting and unique at the same time, so that they become an additional element of our corporate identity.

The kitchen or common spaces are ideal places for informal meetings. It is there that employees spend their breaks, integrate and talk. This means that the noise in this place consists of various sounds in the form of conversations, banging of cutlery and dishes, or the coffee machine being switched on. A high reverberation time (T ≥ 0.8 s) and low insulation of walls and doors (R'A1 ≤ 35dB) result in the spread of noise to other parts of the office and disruption of other people's work.

The purpose of telephone boxes is to provide employees with places where they can conduct telephone conversations freely. They should not disrupt the work of people in their environment. They can be complete mini-rooms or free-standing, mobile constructions, equipped with independent lighting and ventilation systems. However, what is most important is that they are soundproof, provide adequate acoustic comfort and high intelligibility of speech inside.

Auditoriums and lecture halls are rooms that require a special type of soundproofing. We should get the best possible speech intelligibility (STI ≥ 0.85) and even distribution of sound pressure. In the front part, between the lecturer and the listeners, we place reflective panels (amplification and direction of sound). We use absorbing panels on the walls tuned for specific frequencies and profiled scattering (diffusers).

Research shows that adequate acoustics in classrooms contribute to better results in education. Distortion of sound and low intelligibility of speech mean that what is said by the teacher is less well absorbed and remembered by the students (60-70% intelligibility in back desks). Usually, the acoustic background of classrooms exceeds 60 dB, which forces teachers to raise their voice. High reverberation is detrimental to student concentration levels and can cause louder behavior.
