In the past century, scientific activities have been associated with universities or other academic organisations, (government) laboratories, or in the research & development of companies. However, in the past few years, there have been scientific projects that do not fit in with traditional science and have used the collection of “big data” to solve scientific problems. In the Netherlands this is also referred to as "citizen science". It is scientific research carried out in whole or in part by volunteers, often in collaboration with or under the supervision of scientists with an academic appointment. The volunteers may or may not have had scientific training and the tasks may vary from observations, measurements and calculations, to fully designing and conducting the research. In the case of Tinnitus House, the emphasis is currently on collecting data (crowd sourcing), but scaling up to “citizen science” is certainly not excluded.
