| dc.description.abstract | To develop more lenient environments it is important to minimize the amount of ambient noise. As it is today there is no solution to compare the amount of sound that furniture excites when they’re prone to a force. Therefore the market and producers need a standardized way of comparing the amount of noise that, for example a table-top will make in a open environment. The ambition of this thesis is that it will be a part among other thesises leading to a standard way of measurement of tables. The thesis have been performed at RISE Research Institutes of Sweden. The work contains a business intelligence that will be the foundation of the case study that has been analyzed. The case-study contained a tapping machine, a impulse hammer, a shaker and a steel pellet which were tested in a half anechoic room. The results were measured with accelerometers and microphones. The result was that the tapping machine was considered the optimal method of the ones available, for standardization there would preferably be more supporting facts. There are many factors to be observed and compare their the importance of them. One thing that is very important is the amount of time needed to do the measurement, the reason for this is that the biggest cost is personnel. The amount of measurements is assumed to be many and therefore the cost of the device for the measurement will be less significant. It’s also important to consider if it might be worth developing a new device that can be used for simular tasks, otherwise a simpler more specific device might be more relevant. In summary, to come up with a standardized measurement method there is a bit more work needed, this thesis contains a solid foundation to continue working from. The thesis does not contain any new method but decribes a couple that exist in other branches of industry. Some of the methods are modified to fit the chosen object. The measurements are carried out, evaluated and then compared to one another. | |
