All Almedahls curtain fabrics, carpets and some of our roller blind fabrics have been acoustically tested according to the standard SS-EN ISO 354:2003.
In a room with few sound-absorbing materials the reverberation is long and the environment feels acoustically hard. Too long a reverberation time will reduce the speech comprehension and will increase the sound level and the duration of noisy/irrelevant sounds. Such a sound environment may be suitable in certain cases, for example choir singing, where a long reverberation carries the tones.
By increasing the absorption in for example a landscaped office you could reduce undesired sounds like telephone conversations at other desks, fan sounds from a computer etc. Textiles subdue such sounds owing to their good sound absorbing capacity.
In comparison with other sound absorbents on the market, textiles have several advantages. They function as decoration, can be used in many flexible solutions and are cheaper and easier to install than other sound absorbents.
