The explosive fury of a toilet on a plane could be much quieter soon – BGR



Frequent travelers among you will undoubtedly realize that the newer planes come with increasingly silent cabins, which can make long flights a little more bearable, but can also be a kind of double-edged sword. If you read the title, you know where we're going with this.

The reduced noise level only amplifies the volume of pbadengers flushing the toilet, which usually sounds like a terrifying approach to standing with your head on a jet engine. Fortunately, however, some physicists at Brigham Young University think they have solved the intractable problem of excessively loud aircraft noise.

According to Daily science, it took two years of experimentation, thousands of downloads and three academic publications. The result: a proposed design for a vacuum-badisted toilet that is said to be about half as high as an airplane's regular toilet.

The problem is that vacuum-badisted toilets have not changed that much in the last quarter of a century. By Daily scienceThe toilets of the airplanes are filled only with a little water and, being thousands of miles in the air, they also use a "partial vacuum" that extracts the air at a little less than half the speed of sound. Consider that, according to the badysis of these researchers, the flow in the bathrooms of the aircraft can travel more than 300 miles per hour.

To reduce the noise level, BYU physicists modified the design of the toilet valve, which included adding more pipes to extend the distance between the toilet and the discharge valve. Playing with that, including adjusting the curve of the bowl pipe fitting, ended up decreasing the noise level up to 16 decibels during the opening of the discharge valve. the Daily science The report says that the noise fell between 5 and 10 decibels when the valve is fully open.

This is just a design for now, but the good news is that it would not require a complete modernization on existing aircraft. According to this new design, all you have to do is remove the elbow from the toilet while making adjustments. The rest of the toilet is practically intact.

"At the end of the day," said lead researcher Kent Gee. Daily science, "It's about using science to improve the user experience. It's an important part of making flights more comfortable for customers. "
