Sound-insulation doors

Noise-reducing doors: safeguarding health

When planning any building, sound insulation is a central issue. Loud sound waves can have a negative impact on health – and can lead to hearing loss, balance disorders and sleep disturbances. Sound-insulation doors protect people from the stress and adverse effects caused by high interior noise levels from sound transmission. Legislation places limits, for example, on what level of noise generated by a plant room can be heard in a neighbouring office.

neuform sound-insulation doors are designed in line with applicable standards. They reliably attenuate sound in diverse types of rooms, preventing excessive noise. After all, noise is among the most aggressive stressors encountered in our day-to-day lives. The right door from neuform establishes a quiet zone – creating the ideal conditions for focused work, for confidentiality when discussing sensitive topics, or simply for more relaxed living.
