Airborne & Impact Sound Testing in London

Sound Testing usually needs to be carried out between pairs of rooms separated by party walls and/or floors. Most sound tests are carried out between living rooms and bedrooms as these are classed as the two main habitable rooms; however, other rooms can be used if this is not possible such as studies, kitchens and dining rooms.

Our Sound insulation testing procedure is fairly simple and straightforward. Essentially, for party walls there is only one type of sound insulation test which is airborne sound test; however for party floors there is a requirement for two types of sound insulation testing – airborne & impact sound testing. Here is a brief description for each type:

Airborne Sound Testing in London

Airborne Sound Testing is carried out by means of a loudspeaker emitting a steady source of noise on one side of the partition (wall or floor) to be measured. The corresponding sound level is measured on the other side of the partition. Impact sound insulation tests are carried out by means of a tapping machine placed on the floor sample to be measured and the noise measured in the room or space below. Calculations are done based on these measurement and the above mentioned parameters are calculated and compared to the Building Regulations Part E sound insulation requirements for the given type of the building. It is important that the building to be sound tested is completely finished and sealed with no sound leakage through doors and windows.  Please see our check list for sound testing for more information.

Airborne sound insulation testing is undertaken to walls & floors. Firstly a controlled noise is generated by an amplifier and loudspeaker across a broad range of frequencies. The generated noise is very loud and is often in excess of 100dB. Initial measurements are taken using a class 1 sound level meter within the ‘source room’ followed by further measurements in the ‘receiver room’ on the other side of the wall or floor under investigation. The source room speaker position is then changed and the measurements repeated either side of the partition under test. Thereafter background noise measurements are made using a class 1 sound level meter in the receiving room and are used to apply appropriate corrections for external sound such as traffic noise. Similarly the reverberation time (the time taken for sound to decay by 60dB) is measured within the receiving room using the sound source and a sound level meter to determine the corrections that must be applied to account for the characteristics and absorptiveness of the room. The difference in the two airborne noise levels (for walls and floors), corrected for background and reverberation characteristics determines the airborne sound insulation performance of the wall, or floor. A greater airborne noise difference between the source room and the receiver room determines a higher airborne sound insulation performance.

The time taken to undertake sound testing varies from project to project as no site is exactly the same. Taking into account standard site conditions a set of tests on houses -two airborne walls will take one to two hours. A six pack of tests on flats – 2 airborne wall tests will usually take between one and two hours, although this is dependent on our engineers having full free uninterrupted access between all the units/rooms under investigation.

Impact Sound Testing in London

Impact sound testing is undertaken to floors only. This test is different; a calibrated Norsonic ‘tapping machine’ which comprises of five ‘hammers’ driven up and down by a cam and electric motor is used to “tap” the floor surface by applying a known force on the floor structure. The machine is placed in several pre-determined positions. The resulting noise is measured in the dwelling below, using a sound level meter. Thereafter, background noise measurements are made using a class 1 sound level meter in the receiving room and are used to apply appropriate corrections for external sound such as traffic noise. Similarly the reverberation time (the time taken for sound to decay by 60dB) is measured within the receiving room using the sound source and a sound level meter to determine the corrections that must be applied to allow for the characteristics and absorptiveness of the room.

The time undertaken to test each project varies from project to project as no building/development is exactly the same. Taking into account standard site conditions a set of tests on houses which consists of two airborne walls will take approx. 1-2 hours. A six pack of tests on flats consisting of 2 airborne wall, 2 airborne floor and 2 impact floor tests will usually take approx. 2-3 hours, although this is dependent on our engineers having full free uninterrupted access between all the units/rooms under investigation.

Air conditioning is an increasingly common item in the entire house globally

A few years back it was considered an expensive equipment and extreme luxury. But, now its price has become popular due to the development of new technologies.

Location of the evaporator  

The installation of the evaporator (internal equipment) must be chosen with care. It is indicated that the airflow is parallel to the largest dimension of the environment. In addition, you should avoid installing the evaporator away from heat sources and electronic equipment, because of the risk of drainage failure and start dripping water on the equipment.

Condenser installation location  

To install the condenser (external equipment), you must take into account the position of the evaporator, in order to rationalize the use and pipes. Another tip is to place the condenser in place with the lowest incidence of sun possible. Place in a well ventilated place and avoid alleys, corridors and garages.

Water drainage  

Water drainage is another essential care. The drainage process is by gravity, so you should avoid the following problems

Inspect your roof several times a year

To keep a roof in good condition, it is necessary to inspect all the elements constituting this one. Among them, there is the frame and screen under roof that are durable and do not require maintenance. There are also attics that are visited several times a year to check the infiltration of water and the presence of moisture under the roof and insulation.

For openings, it is essential to remove leaves and other debris. All this work must be done once a year to avoid problems of sealing and insulation. Subsequently, the roof terrace, including the cladding, must be cleaned regularly.

Tiles, slates and shingles made of wood, concrete, stone and stone are to be maintained regularly. It is different for zinc. Rainwater outlets such as gutters should be inspected at least once a year to check for leaks, clogging and removal of debris.

For large windows as there may be in the living room, you could combine blackout curtains in dark colors with other fine much lighter shades. This can be very handy addition, since the thick curtains can be closed at times more sun and fine can contribute to privacy when it is not necessary to control the entry of light. In turn, it is important to note that the darker colors make the room look smaller and vice versa.

The hiring of the company that offers us the most suitable services to our needs is very important so that our company stays in the best possible conditions. However, there are some issues that we should not forget:

It is important to make workers aware that they stain as little as possible. The more dirty and messy things left by the employees, the more work the cleaning staff will have. Therefore, more time will have to invest in sanitation and more expensive will cost this service in our business. For example, if our office has an office to mop the coffee cups, it would be better for each employee to clean his coffee when he stains it. If we accumulate dirty dishes in the pile, the person in charge of the disinfection work will take much longer to carry out the cleaning of offices. Make sure that the contract you choose, in addition to keeping the office collected every week, periodically clean your company in depth. The curtains, carpets, rugs, kitchens and bathrooms also need a general cleaning done to detail. On many occasions, the disinfection of this furniture must be done with specific machinery, which should be available to the company you select.
