Frequent flyers among you will undoubtedly be aware that newer planes come with silent cabins, which can make long flights a little more tolerable, but can also be a two-blade sword. If you read the title, you already know where to go with it.
Reducing noise levels only boosts the volume of passengers breathing in the toilet, which generally sounds like a scary approximation of the head with the jet in the jet engine. Fortunately, some physicists at Brigham Young University think they have solved the uncomfortable problem of the overwhelmingly loud airline clutter.
According to ScienceDaily, it took two years of experimentation, thousands of flushes and three academic publications. Result: A proposed vacuum device with an auxiliary device that says that it is roughly half the noise of an ordinary airplane toilet.
The problem is that the vacuum cleaners have not changed so much in the last quarter of a century. Per ScienceDaily, the toilets in the aircraft only run out of water – and, as thousands of miles in the air, they also use a "partial vacuum" that pulls the air to somewhat less than half the speed of the sound. Please note that, according to an analysis by these researchers, airflow in the aircraft can travel more than 300 miles per hour.
In order to reduce the noise level, BYU physicists adjusted the design of the intake valve, which included the addition of multiple pipes to extend the distance between the toilet and the flush valve. Playing with this, including adjusting the bend of the fastening tube, ended with a noise level of up to 16 decibels during the opening of the flush valve. ScienceDaily the report states that the noise fell between 5 and 10 decibels when the valve is open to the end.
This is for now only a design, but the good news is that it would not be necessary to rebuild the existing aircraft completely. According to this new design, all you have to do is remove the toilet elbows while adjusting. The rest of the comod remains intact.
"At the end of the day," said chief researcher Kent Gee ScienceDaily, "It's about using science to improve user experience. This is an important part of facilitating flights to users. "
