The explosive rage of a flush in the toilets of an airplane could be much quieter soon – BGR

Frequent travelers will no doubt be aware that the newest aircraft have increasingly quiet cabs, which can make long flights a bit more bearable, but can also be a double-edged sword. If you read the title, you already know where we are going with that.

The reduced noise level only amplifies the volume of passengers flushing the toilet, which usually sounds like a terrifying approximation of standing head in a jet engine. Fortunately, some physicists at Brigham Young University think they have solved the intractable problem of the loo too noisy aircraft.

according to ScienceDailyit took two years of experimentation, thousands of hot flashes and three academic publications. The result is a proposed design for a power-assisted toilet, which they say is about half the size of an ordinary airplane.

The problem is that power assisted toilets have not changed so much in the last 25 years. By ScienceDaily, the aircraft toilets only overflow with a little water – and, being thousands of miles in the air, they also use a "partial vacuum" that sucks the air to a little less than half the speed of sound. Consider that, according to the analysis of these researchers, the flow in the toilets of an airplane can move at more than 300 km / hour.

To reduce sound levels, BYU physicists refined the design of the toilet valve, which included the addition of additional pipes to extend the distance between the toilet and the flush valve. By playing with this, including adjusting the curvature of the bowl pipe attachment, the sound level was eventually lowered to 16 decibels while the flush valve opened. the ScienceDaily The report indicates that the noise fell between 5 and 10 decibels when the valve is fully open.

It's only a design for the moment, but the good news is that it does not require a complete modernization of existing aircraft. According to this new design, all you need to do is remove the elbow from the toilet while making the adjustments. The rest of the dresser remains almost intact.

"At the end of the day," said Kent Gee, principal investigator. ScienceDaily"It's about using science to improve the user experience. This is an important element to make flights more comfortable for customers. "
