iKoustic Absorption Raft Note 02 0

Do you have a spacious environment that wants to keep the atmosphere of free-flowing visual space, but want to make sure that the internal acoustic quality is of the highest standard while fitting alongside the room’s dynamics? Dropped Note™ can be suspended from a great height to accompany different ceiling levels to reduce reverberation by exposing all surfaces for maximum coverage.

Whether the design is to create a particular relationship with space or to be incongruous – Dropped Note™ can be custom designed and is available in eleven different colours, or you can choose from our in-house stock designs of Rounded or Square. Dropped Note™ falls into the Class A Absorption rating.

Dropped Note™ Information

  • Stock sizes available in Squared, Rounded
  • Noise Reduction Coefficient of 1.00 (average of 100% across all frequencies)
  • Made from 100% polyester fibres
  • A durable structure providing long-lasting stability
  • Available in 11 different colours


No matter your profession, or to what stage you are at with a project – we all need some inspiration from time to time to remind us what else is available. So if you are always looking at the same old sound absorption options glued to the wall in the same Cream colour to match the walls – let us tell you now, there is a lot more out there!

We have chosen a select case study below to demonstrate what is possible. Maybe there is something you like but would like to alter slightly, perhaps there is something you dislike or the perfect design, but all you want is a different colour – whatever it is, we can help you narrow your options and discuss them with you!

Have your own idea?

So you have your idea but want to know how to take your thoughts from paper to see them hanging in the physical world – installed in your space? We want to hear them!

Our in-house design team can help you every step of the way by bringing them to the physical world as we look at how each idea is best structured and how it will fit together,

Then we create visualisations of each space (both existing spaces or new spaces alongside the architect’s visualisation) to see how they will look in placement. We then send this off to our cutting team who have state-of-the-art precision cutting tools – and then finally we send these flat packed to your installation team, or our installation team if you’re looking for the whole package.

We offer a bespoke product tailoring for our Dropped Note™ with our in-house designer to help cater to your requirements.

Want to learn more about Reverberation?

With all the terminology associated with the world of sound, from sound transmission to reverberation – we do our best to turn information that is based on the mathematics and physics to present it and educate as best we can to those that are not all that certain, or are dipping their toe in for the first time. We all had to start somewhere, and this is what we aim to do – we want to feel comfortable with the knowledge available to help you choose best. It is important to remember that reverberation is created in a single space, a hall for example with hard and reflective surfaces to where the sound continues to bounce around untreated thus creating a long decay of any sound produced. Reverb is addressed by the addition of absorptive materials, helping to absorb sound waves across the frequency spectrum and turns the sound energy to heat – dissipating its acoustic energy.

Reverberation is also be affected by a room’s geometry and size, and will often require considering these in addition to its reflective surfaces. When we dig a little into the background, you will find terminology, mathematic equations and names of Scientists you have never heard of – and in the information age, most seek to understand a little more background of what we are trying to solve. We have put together a brief explanation of reverberation to help cover the standard terminology that often accompanies it and describes the adverse effects of excessive reverb in inappropriate places. Reverb above tolerable and targetted levels can disrupt adequate levels and is found to have adverse detrimental effects in educational environments and critical listening and performance spaces. We aim to update this with new research and provide blogs on areas revolving around reverberation. Click on the link below to read more!

Is it suitable for my space?

You have the challenge of introducing Sound Absorption products to a spacious environment that requires a significant improvement in the acoustic quality of a room while trying to breathe life into a setting but wondering if it is suitable for your project? If it is an internal space, then you have your answer, Dropped Note™ applies to a wide range of indoor environments from high ceiling café and co-working spaces to leisure centres and swimming pools.

  • Offices and Workplace
  • Environments
  • Home
  • Restaurants
  • Bars
  • Nightclubs
  • Cafés
  • Retail

Each Dropped Note™ is precision cut to provide a stunning level of consistency, and for ease of fitting, it is flat packed with suspension wires and adequate fixings with instructions for fitting – that is if you fancy yourself a DIY enthusiast, if not we have an installation team happy to help put these in place for you!

The physical properties of space; the size of it, to the geometry and the material composition internally all lend to painting the soundscape in a particular way and influencing reverberation in both positive and negative ways – depending on it’s intended usage. Large, open spaces with no sound absorption materials or soft furnishings that want to conduct lectures and discussion groups may find that the acoustic conditions are unbearable. You are recognising that you are regularly raising your voice over your own, or others, or you are struggling to hear a word the speaker is saying – even with the use of a PA. In short, we need to know what sort of activities are planned in your space, whether they exist now or proposed and to take details of the following – for there is no one solution for any repeat measurements of any one of the points – no two rooms are the same.

The room size.

Geometry, for instance, pitched roof with an octagon shape would have a completely different trajectory of sound than a simple rectangle room with a flat roof.

What each surface has as a building material, for instance, a polished wooden floor with exposed breezeblock walls and a wood panel ceiling
First, we aim to create an estimated acoustic modelling of the room or look to carry out an Acoustic Test, we then we look at required levels alongside your budget in mind for introducing Dropped Note™ to your space and discussing any visual requirements you may have in terms of colour scheme and their arrangement.

Dropped Note™ is not suited for the reduction of airborne noise issues, these are: conversations coming through partitions, overhearing televisions or music – they are for treating the internal acoustics of the room to improve the quality of speech and listening in general, as well as reducing the domestic ambient noise levels from being amplified in an open environment. It achieves this from being a lightweight, fibrous material that is suspended from the ceiling to create a cavity to which increases its acoustic performance of reducing reverberation in a space. But, it is often required in a vast range of scenarios that both soundproofing efforts go hand in hand with sound absorption materials to create good sound control across the board.
Dropped Note™ is made of 100% Polyester Fibres which makes it safe for almost any internal application for there are not exposed irritants or loose fibres – of this 65% comes from Post Consumer Recycled Content with 35% from Pre Consumer Recycled PET fibres.

Modern design approaches to the hospitality sector have progressed with the aesthetics drawing from a minimalist design: exposed concrete flooring, brick and block work walls all cragged and left to the elements with lots of hard furnishing. And in restaurants we are often seeing the kitchen environment opened up, to create an exposed and lively environment – creating engagement between Chefs and the customers by including them in the atmosphere, allowing them to be part of the experience.

But, with this comes the noise created in kitchens that were once hidden away behind the small porthole door beyond the bar is now central – so we now have the free-flowing environment being subject to the noise issues found in kitchens reverberating around the dining space. Dropped Note™ is a simple but beautiful addition to remedying these noise issues in a way that controls the background noise level – and is perfectly acceptable in cooking environments. The only initial suggestion we do have is to look at darker colour schemes where placement is required in areas with excessive vapour and smoke for staining will occur over time.

Dropped Note™ is straightforward to install and is accomplished by using the included suspension wires – depending on your desired drop extension cables may be required in which we can assist with.
If you want stars, 2D Giraffes or simple triangles cut out and hung throughout we can put this together and help you visualise this by rendering your proposed or existing place to see it in placement.
