With modern tech being what it is, why do the captain/crew on new airplanes still sound like they’re eating the microphone?
In: Engineering
Because communication technology to be used was written into law in the 1970s?
What region is this? Nice to see VZW expanding their NR configuration. Is this SA too? Id like to see how it compares to AT&T CBAND/DoD config.
A: the pilots generally can’t hear what it sounds like in the rest of the cabin. 2: they aren’t trained vocalists used to the specific sound envelopes and ranger for their microphones. Lastly: the speakers on plants ain’t great.
That being said, I’m still amazed I can understand pilots but still have to muddle my way through grocery store announcements that I literally cannot decipher.
Edit: This is what my friend who is a pilot told me.
Speaker tech and microphone quality are arguably worse than 40 years ago., regardless of the technology increase. The systems in airliners are cheap sound systems. Also, the pilots don’t get feedback as to what is sounds like while transmitting on the PA, so they can swallow the mic and not hear it well.
I work on some of the biggest and newest container ships in the world. We have the same problem with our PA system
The reason I have found so far is: you are eating the microphone. They have some sort of mechanical passive background noise cancellation, that if you are to far away (more than 1.5cm from mouth to microphone) then the sound in the recievers end is very poor. So the easiest is just to (almost) eat it
