SALLE JACQUES TATI (Performance Theater) – www.mjctati.org
Orsay (91) (2005-2007)

The Salle Jacques Tati is renowned for concerts, theater, and community performances. In 2005, Marie-Hélène Aubry, the Mayor of the town of Orsay, decided to undertake the challenge of the complete renovation of the theater. Michel Cyprien, the director of building services for the town of Orsay, was the construction coordinator. Mr. Paul-Marie Guyon, Director of research at the LCAM-CNRS (Université Paris Sud) also in Orsay, had proposed that the renovation should include acoustic treatments that would improve both the musical experience but also improve the speech intelligibility for the hearing impaired during theatrical performances. Our senior consultant was chosen to model the room and develop the acoustic designs. The models were produced with proprietary software. The results have been very well received as is apparent by the testimony’s below.

Salle Jean Renoir (Salle polyvalente)
Bois-Colombes (92) (2006-2008)

The town of Bois-Colombes had long envisioned the opportunity of someday renovating the performance hall "Salle Jean Renoir" that is nestled in an affluent residential section of the town only minutes away from town hall. Proximity in this case was equally an advantage and a disadvantage, and for that reason sound isolation was a priority. Careful acoustic designs were required for all of the various activities the hall was supposed to accommodate, including amplified music, non amplified music, film projection, theater performances, and general public meetings. Working in collaboration with M. Pascal Luquet from the acoustic consultancy "Bien Entendu" and the architect Jean-Pierre Laubal of the architectural firm "Equipage Architecture", our consultancy brought onboard both our experience and our proprietary software for optimized acoustic design for speech intelligibility, along with several specific software applications developed for music clarity/envelopment ratios for amplified and non amplified music.

CHATEAU LA BORIE - European center for musical exchange (Classical, Baroque, Jazz) www.ebl-laborie.com
La Borie en Limousin – Limoges (87) (2007-2008)

The Chateau "La Borie" is a beautiful and prestigious domain near Limoges in France. It is truly the dream come true for its creators Isabelle Depret-Bixio in association with Christophe Coin and Jean-Michel Laygonie, and today it is proudly the home of the Baroque Ensemble of Limoges. There are more tha 16 people on site at the chateau who are responsible for organizing concerts, tours and hosting the musicians who are invited to the chateau for a "period in residence". These visits offer a chance for musicians to compose, rehearse, record and perform in the concert hall for the public.
Our consultancy was chosen to design specific acoustics for the concert hall that would provide excellent envelopment and balanced spectral content for both classical music and amplified jazz. This required a passive variable acoustic design. The project also included the creation of a recording environment in the large room with module mobile rolling panels that offer up to eight isolated spaces along with a control room for stereo recording and mixing that was installed in a large room next to the concert hall.

We were contacted to use our software to model the classrooms and proposed treatments that lower the occupied noise and raise the speech level in the rear rows of seats. The S/N ratio (speech to noise ratio) can be increased by between 5 and 12dB depending on the seats. A target of better than +8 dB was achieved for every seat with over half of the seats being greater than +10dB S/N. Additional acoustic features could increase the S/N by 2 to 3 dB and will be incorporated into a future phase of renovations. Essentually as you move farther toward the back of each classroom the speech level increases.

CHINKEL – www.chinkel.com
Paris (75)(1999-2000)

The management at Chinkel led by Gregoire Parcollet found 3 medium sized warehouses in the center of Paris near Pigalle. They were side by side, so with the architect Mr. Gerard Turk they joined the three buildings creating one very large space. Our senior consultant was chosen to design seven spaces : a large film mixing auditorium (135m) that could also be used as a dubbing stage; 3 identical 5.1 surround sound control rooms (40m² each) for mixing and recording dialog; a control room (25m²) with its associated OCD vocal room 12m²), a control room for sound editing (18m²). Of particular note for this project was that the principal exterior wall along one side of the main auditorium was in direct contact to a 5 floor parking facility next to the building. The noise isolation design included this problem and the results are NC15. Also, OCD is an abbreviation of “Omni Compatible Design” which refers to the fact that any static condenser microphone can be used in these rooms without resonances or early reflections being imposed on the signals being recorded, for example vocals. Though it is widely known that a good static condenser microphone will generally sound its best when used with the omni directional pattern, but it will also be very sensitive to reflections from surrounding surfaces. This type of vocal room design was created to be especially transparent when recording with and static microphone.

Paris (75)(1990)

Gang studio is an example of a classic French music studio with an exciting history. This project included the installation of additional cabling in the control room and the fusion of two consoles side by side. An API and a Soundcraft were cabled together to function side by side as one single consule. All busses were summed together, stereo buss out, monitor sends, aux sends, even solo and mute functions needed to be linked. Patch bays were added and all in all it was a fun project.


Various Projects (Conference Rooms, Places of Worship, Public Meeting rooms, Athletic training, Restaurants)

INSEP – Weight lifting room
Vincennes (94)(2010)

The INSEP (National Institute for Sports and physical education) was confronted with the problem of extreme shock on the floor of the new weight lifting gym due to the impact from the falling bars weighing between 60kg and 180kg. The height of the fall varied between 60cm and 180cm, so a quick calculation reveals impacts forces varying roughly between 200J and 2000J. The weight lifting room is right above the main conference room so simultaneous activities were impossible. Though the logical solution would have been to install the weight lifting room on the ground floor somewhere else, the direction decided for logistical reasons to find a solution that involved reducing the shock. We were awarded the contract to develop a solution and the results make an interesting read. After the construction of this hybrid shock absorption system a session of sound measurements involving 100kg dropped from 2m failed, as it was now impossible to hear when the weights dropped. A case study paper with photos, plans and measurements will be posted here soon.


INSEP – Dance training room
Vincennes (94)(2010)

The INSEP (National Institute for Sports and physical education) was confronted with a common problem of visual annoyance. We have seen this problem several times before and it consists of a sensation of discomfort when looking toward high contrast black holes in a light colored perforated panel. Visually the annoyance is due to the perception of movement. It is very disconcerting and the only relief is by looking away as the effect continues even from peripheral vision.
Perforated panels are occasionally prescribed as a wall surface with assumed acoustical advantages based on absorption coefficients derived in a nearly diffuse field. Unfortunately the assumption that the perforations offer a certain. Though it is widely recognized that the amount of energy reflected back into the room from any hard surface depends on many characteristics especially the angle of incidence of the sound. It is not commonly acknowledged that perforated panels have a very high reflectivity at all angles of incidence based on the percentage of the perforations and the size of the holes. In this case the walls of the dance training room were covered with perforated sheet rock. The black holes being 8mm in diameter troubled and annoyed the dancers so the Directors of INSEP sought a quick solution for this problem and asked DOT Acoustics to help. A case study article with photos, plans and measurements will be posted here soon.


INSEP – Plateau de Tournage
Vincennes (94)(2010)

The National Institute of Sports and Physical Education (INSEP) has installed a film stage to begin production of training films for sports. The film stage is a 75m² area with 6 meter high ceilings above which will be several classrooms and a main hallway. The questions were will the footfall and furniture movement from above inhibit the filming activities and if so what should be done? The answer was yes for many reasons, and the solutions for each merit a detailed case study that will be available here in late 2010.


Centre George Gorse – Salle de Danse
Boulogne (92)(2007)

The “Centre George Gorse” is a performance arts center with music, dance and concerts in the town of Boulogne on the western edge of Paris. They decided to build a new dance hall (175m²) right above a large lecture hall. Our mission was to design a floor that would completely isolate the dance hall from the lecture hall. We proposed a composite multi layer floating floor (15cm thick including the dance mat) with a very high damping coefficient; significant deflection and the magnitude of the resonant frequencies are very low. The results are that no sounds or vibrations from the dance hall can be heard in the lecture which has an unoccupied ambient noise level of <28dBA.


Mairie de Hardicourt – Salle de réunion des anciens
Hardicourt (78)(2009)

This large meeting room is regularly used for town meetings and many of the older participants have complained in the past about the noise levels during meetings. The acoustic consultancy Accord Acoustique had proposed that the ceiling be treated with an open cell foam/textile product from TEXAA to be hung as clouds from the ceiling. They realized that a continuous ceiling with a high coefficient of absorption would look much better and offer a better acoustic result for nearly the same price. They also proposed that 50% of the walls be covered with perforated metal panels with rockwool behind them. We were commissioned for the construction supervision and quality control.


Mairie de Hardicourt – Main meeting room in the townhall
Hardicourt (78)(2009)

This meeting room is essentially a cylinder and the acoustic consultancy Accord Acoustique had proposed that it be treated with an open cell foam/textile product from a French company called TEXAA. The thickness of the foam is 20mm and it was to be glued directly to the walls to maintain the cylindrical aspect of the room. We were commissioned for the construction supervision. Sonacoustic was also installed on the ceiling.


Petit Pergolèse – Restaurant sur la Champs Elysées
Paris (75)(2008)

The “Petit Pergolèse” is an up scale restaurant near the Champs Elysée in Paris and they had realized recently that many of their clientele were hesitant to dine there on weekends due to the noise when the restaurant is busy. The management agreed to install a seamless ceiling called Sonacoustic from a company called ASONA. They also agreed to cover a large wall with absorption panels that originally was cover with mirrors. Everyone who remembers the restaurant before the renovations has been surprised by the results.


Troc Quai – Restaurant
Nemours (77)(2008)

The « Troc Quai » is a popular new restaurant in the French town of Nemours and they had endless complaints about the noise levels when the restaurant was full. For this project we suggested that they cover the ceiling with an ASONA product Sonacoustic, which is a seamless ceiling product with a very high absorption coefficient. They opted for both the ceiling modification and custom built wooden structures, with very absorbent sides that segmented the dining area into small sections that we also recommended, as reflections from the ceiling were only part of the problem. The results have been very well received and the restaurant now has no equal in the town in terms of quality and comfort.


Church - Saint-Mathurin de Larchant Larchant (77)(2010)

In the small village of Larchant, France, there is a church called the Saint-Mathurin de Larchant, and it has been the property of the chapter of Notre-Dame de Paris since 1005. It was rebuilt beginning in 1153, and was served as the original prototype of today’s Notre-Dame de Paris. The church became a popular pilgrimage site, which Harry Bailey, host of the Tabard Inn of Chaucer's Canterbury Tales was recalling, when he swore "by that precious corpus Mathurin". The church was seriously damage during the religious wars by Gabriel de Montgomery but the main vaulted sections have been beautifully restored. The ceiling is 17m high and so the reverberation time being >5 second is to be expected. When the association that handles the ongoing restoration of the church contacted us they simply said that the speech comprehension during the services was very poor. We proposed a dual solution : 1) Add 200m² of an absorption product that looks like stone (alpha 0.85) and 2) organize a community project with the design and assembly of a custom sound system. The project included help from a group of teenaged students from the area that were invited to help with the construction and installation of the custom designed loudspeakers that we designed. A local cabinet maker proposed to cut the materials for the loudspeaker cabinets. Once the sound system was installed and calibrated, the entire congregation from 25 to 95 years old began to offer their heart felt satisfaction in the listening comfort that the new system offers.
