Acoustic solution for cinema

From past to now until the next hundred years or more, cinema stills the
entertainment for all ages and inclinations which strongly needs a clear sound reaching the listener’s ear. And we all want a convenient, favourable, and pleasing sound. But What should intender do, then?
Figure out the best locations for the screen, seating, AV components and
speakers and determine what type of acoustical treatments can be used to help improve the sound.

Let us focus on the situation of sound wave in the cinema hall.
Sound waves will travel from the speakers and bounce off of just about any flat surface in a room. The ceiling, walls, floor, etc. Contained within a cube room, it is more likely for standing waves to occur. ”A standing wave is a low- frequency resonance (reinforcement of sound by reflection) caused by a source wave colliding with a reflected wave of the same or similar frequency”.

So, it should be mitigated because they can cause three different acoustical
issues:

• An area of high pressure where there is a very noticeable increase in volume.
• A resonating sound wave. Sounds extending for longer than they were
  intended.
• An area of low pressure where there is a very noticeable decrease in volume.
  Even the most expensive sound system available – resulting in poor quality with
  hard to make out dialogue and exaggerated bass response.
  There are several golden rules which should be applied to the design of the room to ensure the best possible audio experience.
  How do Acoustima® acoustic panel by Seatup Turkey® provide Acoustic solution for cinema:
  First of all, sound transmission occurs through doors and windows so there is always just one small door in the corner of the cinema.
  With regard to shape, Go with the rectangle space. Practically speaking, you’ll have better seating and furniture placement options. Technically speaking, rectangular spaces lend themselves to better sound than square rooms that can create annoying resonances and other sonic problems.
  In order to avoid echoes completely, the surface shapes must be created so as to diffuse or absorb the incident sounds. Multiple reflections between two parallel planes may cause flutter echoes. Although it is easy to avoid them by making the two planes non-parallel or the surface undulated.

About size, there are so many different recommended ratios for size out there that deciding on which one is “right” can be difficult so any one can offer good performance.

Other important issues:

Sound waves and acoustic reflections can influence essentially sound from the speakers should not reflect back on the same path but dissipate naturally, which can otherwise cause a muddled or bass-heavy sound.

room structure: the walls should be constructed closer together in the front

(where the display will be located) and further apart near the back of the room.

This will help tremendously with the acoustics of the room. Sound waves

typically bounce more when they meet a 90-degree corner of a room.

After designing size and shape of the structure, the next basic step for Acoustic solution for cinema is Insulation.

Sound is transmitted mostly through walls and floors by setting the entire

structure into vibration. This vibration generates new sound waves of reduced intensity on the other side. The passage of sound into one room of a building from a source located in another room or outside the building is termed ”sound transmission”. Sound insulation describes the reduction in sound across a partition. The sound insulation across a good conventional, lightweight, office to office construction is typically in the order of 45 dB. That happens by adding acoustic materials which have high sound absorptivity in the construction phase.

Acoustima® acoustic panel by Seatup Turkey® use other tools to get the best possible sound. Which is the final and core step, acoustic panels.

A full outer skin of Acoustima® acoustic panel by Seatup Turkey® sound

deadening can ensure sound does not leak into adjoining rooms which has the advantage of ensuring sound levels are maintained in the room.

Fortunately, there are several ways to absorb the sound and mend it in the

lounge for a unique sound experience, as Acoustima® acoustic panel by Seatup Turkey® we improve products to solve this kind of problems (Acoustic solution for cinema).

By using acoustic panels which make a special role in blocking, absorbing and minimizing the sound waves. So that treat echo and reflection.

As it turned out, acoustic panels or acoustic fiber can be fixed on floors, walls,
ceilings, and furniture. Using available surfaces to benefit from the place.
However, one of the important cinema projects that Acoustima® acoustic panel by Seatup Turkey® improves is the Cinetima Cinema in Bursa Özdilek parkı. In this cinema, as the photos show, one of the halls its wall has been covered with high-acoustical properties wooden panels in sloping shape and there is LED light between panels by Acoustima® acoustic panel by Seatup Turkey®.
Moreover, Acoustima® acoustic panel by Seatup Turkey® has added the
acoustical carpet and doors. In addition to the comfortable design of the seats which has also acoustical properties which you can find in the cinema and movie catalogue:

also; added Acoustima® acoustic panel by Seatup Turkey® the seats in the
reception hall with acoustical properties which has the circular shape that helps in saving the space.

In Bursa, you can notice two more special acoustically designed like
Cinemaximum cinema in Suryapı and Carrefour shopping malls where these cinemas’ reception halls have special metallic suspending ceiling with acoustical properties. Also, Avşar cinema in AS Merkezi and Kent maydani shopping malls where these cinemas have colorful acoustically designed cinema halls.

As a summery; Acoustima® acoustic panel by Seatup Turkey® can help you in different, modern, and acoustically designed cinema. Also, you can see our online catalogue:

Acoustic solutions for Museums:
Our Acoustic solutions for Museum can be see now in One of the most marvellous exciting places in Bursa / Turkey to visit, it is the Panoramic
Museum in Bursa and it is the largest full panoramic museum in the world that consists of a main theme revitalization hall, exhibition halls and meeting rooms, cafeteria, and administrative departments.
The foundation was laid on 15 September 2015, On November 1, 2018, was
opened. Construction area: 4.500 m² / Usage area: 8.388 m²
The panoramic museum is telling the story of the history of Bursa from the day that the old city has been conquered by the Ottoman, and as well the story of the 6 Ottoman sultans who buried in Bursa.
In the entrance of the Museum you can find 16 paintings describing the social life in their time. of the big 6 Ottoman sultans .

Can you imagine the noise which can propagate there?
Acoustical and physical researchers appreciate the reverberation time of this kind of climes about 11 s. In other words, noise pollution.
This value is due to many factors, let us analyse them one by one:

And then see how our Acoustic solutions for Museums can help …

1. Enormous space volume which is proportional parameter to reverberation time.
2. The existence of reflection surfaces.
3. Low sound absorptivity because of the lack of areas that have high
   absorption coefficients.
   The impact of noise on workers and visitors as well can cause serious health damages and problems.
   So how can they adjust this to make cosy place to sound?
   Acoustima® found Acoustic solutions for this Museum by applying perfect sound insulation and noise reduction by consultation specialist acoustical engineers.
   The operation needs two basic steps the first one deals with architectural acoustic (the science and engineering of achieving a good sound within a building and is a branch of acoustical engineering.), in other words, the structure, shape, size, and constitution of the building. On the other hand,
   whereas, room acoustic is considered a strongly effective solution that depends on additional components have high sound absorption coefficient reach up to 0.9 which called ACOUSTIC PANELS.

Acoustic solutions for Museum by using Acoustic panels are sound absorbing panels that are hung on a wall or ceiling to control and reduce noise, eliminate slap echo in a room. The objective is to enhance the properties of sound by improving sound quality and soundproofing which concludes any means of reducing the sound pressure with respect to a specified sound source and receptor.
These sound absorbing panels come in a large variety of sizes, types and
colours to meet your design, budgetary, and durability requirements.
Absorbing sound spontaneously converts part of the sound energy to a very small amount of heat in the intervening object (the absorbing material), rather than sound being transmitted or reflected. There are several ways in which a material can absorb sound.

The choice of sound absorbing material will be determined by the frequency distribution of noise to be absorbed and the acoustic absorption profile required.

in the museum:
To apply Acoustic solutions for Museum at the first floor; you can see the
auditoriums which display a movie about the ancient culture of Turkey, you can notice that the auditorium is acoustically designed by adding perforated, wooden acoustic panels on the walls which efficiently absorb the sound by means of reducing the noise in the Auditorium.

Also; there are wooden suspending ceiling acoustical panels which it absorbs sound.in addition; it contains acoustical seats generally made from foams and has high acoustic properties, and each auditorium has a Soundproof acoustic door which commonly made from wood are an ideal cost-effective solution because it does not need much coating but absorbs sound by its self moreover, they are suitable for a wide variety of applications in any room, office or hall.

out of the auditoriums; there is a big field in the middle designed as non-
parallel wall; it has a semi-circle shape; the walls’ shape can highly kill the
reflected sounds thats lead to minimize the noise and the reverberation time inside it.

this field look like a small amphi-theater and the stairs has seats with
acoustic properties, the ceiling is full with the wooden acoustic panels which have the shape of compact slats has a very small gap between each others, aproximmetly thes panels has NRC value around 0.88.

On the right hand of the field, there is a small fair shows the green tomb tiles that used in building the historical green mosque in Bursa. This type of tiles represents the first ceramic art in Turkey. These ceramic tiles was used to improve the acoustical and thermal performance of the floating floor to reduce the walking noise side by side of giving the place an unique, wonderful and surprised aesthetic view.

Next to the fair there is a gift shop, has a cylindrical shape with also wooden suspending ceiling and its roof has un expected, huge and fantastic optical acoustical canopy in the middle of it which plays an important rule in the acoustical control by means of provide a comfortable and un-noisy corner with also high-quality, simple shape and colourful seats at the roof of the shop.

On the other side, you can notice a library contains some wooden tables and foam chairs, there is also wooden shelves contains numbers of historical books, and its ceiling is installed by the same acoustic panels at the interring hall in the middle of the museum.

Finally, in the corner you can notice a small cafe to take a rest after this
interesting tour inside the museum, which bring comfort inside you by its
design which has wooden tables, wooden acoustic panels on the ceiling and
wooden bar as well as the foam seats has a brownish color which perfectly
goes with the wooden tables.
In the second floor there is the panoramic part that depicts the conquest day in a 360-degree circular cycle and tells the journey of Bursa from Beylikdian to Cihan State.

This new museum that opened in 2019 can tell us how much is the Acoustic
solutions for Museum important to give the comfortable environment without any ambient noise to the visitor and achieve the mission of the project successfully.

how to combine Led lighting in the acoustic panels and Cinema hall ?

The idea of combine and install led lighting in the Cinema hall and even in Auditorium hall is a quite familiar to you as I guess. We all know that it is adding very fancy look to the cinema, but how to decide the design and shape?

First you need to analyze the size of your movie theater /Cinema hall.

Does it has stairs? In the cinema hall, a line of LED lighting is installed on all the stairs.

But if it is a conference hall or Auditorium, there is no need of line on each step,

but you can install the LED on every 3 or 4 steps.

The importance of LED lighting in the cinemas on the stairs is especially  to help the audience

to orient themselves in the space especially when they arrive after the lights in the hall have been turned off and the

stair lights warn them not to fall. In some cases, there are no stairs in the hall, and in such a situation, the LED

lighting should be installed to the extent of the hall around it.

Of course when it comes to a movie theater  and cinemas after  the film has been started all the lights are turned off

including the LED light and it is lit again towards the end of the movie or during commercials.

And there is also the LED light that is inside the wall between the acoustic wall panels. Such lighting adds a great

deal of aesthetics and a look of luxury to the hall.

You can design straight and short lines horizontally or vertically. And if you want something more special then you

can draw diagonal lines or literally shapes such as hexagons and more.

What is important is that the owner of the cinema has simple and fast control over turning off the LED lights, since

they can sometimes be too harsh to the eye or simply need to be switched on or off. It is highly recommended to

create a few separate lines in the hall so that it is not just one switch that turns off everything at once but rather has

to be separated and divided between the lines in order to create control over the amount of LEDs you want to turn on

and off. This will give you more flexibility to decide how much you want to light each time. Depending on changing

situations, you may choose to use a larger or smaller amount of LED lighting so that as many lines as possible are

separated in the hall. This will also allow you to design the hall with a different color LED bulb and you can also use

it as a sign. For example, you can determine that when a red LED appears, this is a commercial break and when

blue LED turn on then it is a sign that the movie is about to start soon, etc.

If so, let us say that the LED light is not only an aesthetic and impressive design but also an important tool in the

cinema halls in order to warn visitors from the stairs in the dark hall and also to mark different things to them.

However, LED lighting is a particularly good option in order to prepare the hall for fancy look and impressive style

that attracts visitors.

We manufacture Acoustic panels and chairs for cinemas and will be happy to help design and install the LED lighting

between the panels in the wall  or by the lighting strip on the stairs.
