Direct Fabrics Acoustic Curtains Presentation. Understanding Acoustic Curtains & Soundproof Curtains

www.direct-fabrics.co.uk/curt...
The video is a presentation by a company called Direct Fabrics discussing the topic of understanding acoustics and their curtain products designed to address acoustic issues. The speaker, Edward Simon, who is the director of the company, explains their approach to solving sound-related problems and highlights the importance of using certified products.
The presentation covers the following points:
Understanding Acoustics:
Acoustic absorption: Explained as the process of sound energy being converted into heat or kinetic energy by various materials.
Testing methods: The company's curtains are tested and rated based on acoustic absorption and sound transmission.
Curtain Products:
Two-layer curtain: Weighing around 800 grams per square meter, it offers 11 decibels of sound reduction and is suitable for room dividers and window treatments.
One-layer absorption curtain: Weighing around 400 grams per square meter, it reduces echo and reverberation in recording studios and open-plan spaces.
Three-layer or more curtains: Weighing around 1200 grams per square meter, these provide maximum acoustic absorption and are recommended for room dividers.
Effectiveness of Curtains:
The curtains are tested and certified, providing thermal and blackout benefits along with sound reduction.
They can reduce sound transmission between rooms and offer a noticeable improvement of around 3 to 7 decibels depending on the specific setup.
Pricing:
The presentation provides price ranges for different curtain configurations.
Next Steps:
Customers are encouraged to speak to the team for personalized advice and quotes.
Free samples are available for customers to assess the products.
Overall, the video presents the company's curtain products as effective solutions for addressing acoustic issues in various settings, including residential and commercial spaces. The company emphasizes the importance of using certified products and highlights their commitment to providing reliable and high-quality acoustic solutions.
The products mentioned in the transcript have been tested using two different tests:
EN ISO 354 Acoustic Absorption Test:
This test is used to measure the acoustic absorption properties of a material or product. It involves placing the material in a reverberation chamber, which is a large room with hard, reflective surfaces. Sound is introduced into the chamber, and the time it takes for the sound to dissipate is measured. By comparing the sound decay with and without the tested material, the amount of sound absorption provided by the material can be determined. The test yields an absorption coefficient ranging from A to E, where A represents the highest level of absorption.
EN ISO 717 Sound Transmission and Acoustic Insulation Test:
This test assesses the sound transmission and acoustic insulation properties of a material or product. It is conducted by placing the material between two reverberant rooms separated by a common partition. Sound is generated in one room, and the sound level in the receiving room is measured. By comparing the sound levels with and without the material in the partition, the product's ability to block sound and reduce sound transmission between spaces can be evaluated. The test yields results in decibels (dB), which represent the level of sound reduction achieved by the material.
These tests help quantify and verify the acoustic performance of the curtain products, allowing customers to make informed decisions based on the products' sound-absorbing and sound-blocking capabilities.

Very informative and transparent with science to back realistic claims.

Thank you. The team has tried to discuss the relevant test and real world performances. Quite a hard topic to explain. If you have any question or after more information then please contact the team. We have a new range of curtains that is a lower price and a 10db certificate as a room divider and with 2 layers of acoustic lining it does 13db.

@@Direct-Fabricscouk thank you. I've already requested fabric samples with a view for some accoutic curtains to help noise reduction from local airport.

When you say it is 11db reduction as a room divider, do you mean the curtain acting on its own I,e without a wall, door or window between the rooms? We have an open doorway between 2 living rooms and want to reduce the sound across 2 rooms so it would just be the curtain hanging. Also do you do the velcro strips to stop gaps at the sides?

[@Direct-Fabricscouk]

Exactly correct, so this curtain will do 11db without anything else in the testing aperture. So you can expect in perfect sealed scenario of a lab 11db. In real life this will drop a few DB. Estimated in our other videos as 6-8db. You can request an additional layer of the lining which will put it upto 12db. Again this will reduce in real world settings. Any other questions please do not hesitate to contact the team. thank you

Hi I’ve found this video very interesting. Have you tested plated curtains yet ?

[@Direct-Fabricscouk]

Yes the pleated curtains have been tested. There is no uplift above the flat. This makes sense when thinking it through logically. As it will only perform as well as its weakest point. However there will be more absorption for echo and reduction of existing sounds. Our curtains have been tested for absorption in a pleated manner. Again this makes sense as there is more surface area for absorption.
