A museum requires a performant lightning system in order to observe the exhibits in a proper way. Taking a walk in Tate Modern I noticed that the light intensity as well as the light distribution is different in each space: the galleries from the Turbine Hall and the halls. In the galleries there are glowing light boxes displayed on the ceilings. The boxes are made out of glass and a steel frame. In addition to these there are also attached movable light bulbs on the steel skeleton of the boxes. In his article, John Hirst describes the inside of a light box: ‘Internally the boxes have removable sides and top and all equipment needing servicing or inspection is located within arm’s reach of the nearest light box’ (Hirst, 2000, p.30). Due to

The same Turbine Hall is the only space from the museum in which echoes are created because of the enormous size and emptiness of it. Taking a walk through the rest of the building I measured the intensity of the sounds in the exhibition rooms, café, restaurant and halls, using an Iphone application called Decibel 10th. The average intensity of the sound in the exhibition rooms was 60 to 63 decibels, which is also the average of a normal conversation. As expected, the café was the loudest with a measure of 73 decibels and as for the halls and the restaurant, both came up at an average of 65 decibels. I took my first measurements on a Thursday evening when the amount of visitors was average. Coming on Friday at a peak hour, my application noticed a difference of almost 10 decibels in every room of the museum. The exhibition rooms were louder with 7 decibels than the last time and the halls were measuring 82 decibels, the sound intensity of an average automobile. As the predominant material of the walls is concrete and the building, with the exception of the Turbine Hall, is permanently filled with exhibitions and facilities, there is not much of sound absorption or reflection. Because of that, there are no echoes in the exhibition rooms, halls, café or restaurant (Anon, no date). The space in which the sound vibrates and it is reflected are the exhibition rooms which are specially made for cinema or video exhibitions. The sound in these rooms are also louder, up to 80-85 decibels and more often higher in
