It took several months of planning to get all these whistles and special permission to be in Gamla Ullevi in Gothenburg, Sweden. While the loudest whistle doesn't necessarily mean the best, it's an important factor depending on the intended use. Practicality and sound consistency are also important to consider. In this video, I blew the whistles with full force to ensure fairness and I created a race chart to show how they compare in sound level. Most whistle companies do not specify the distance or measurment type when stating the decibel levels of their whistles, resulting in a lack of standardized measurement practices. Some companies use A-weighting while others use C-weighting. I chose to measure the decibel levels from a distance of 0.5 meters with C-weighting. This decision was made considering that some companies measure from closer distances, while others choose 1-2 meters. C-weighting is particularly useful for measuring short bursts of sounds, such as whistle sounds. The sound levels were measured using a professional class 1 sound level meter, the B&K 2245: https://www.bksv.com/en/instruments/h...
