actually I think that the biggest misconception of all is that a beginner should start on an acoustic guitar. It's harder to play on an acoustic. higher action, thicker string gauges therefore harder to string bend and more painful in the fingers (especially for a beginner with no callouses on the fingertips) . If the loud noise and distortion is the issue, get an electric guitar play it clean (without any distortion) and turn down the volume of the amp or better yet, wear ear protection (which I think is always a must). Another thing is that because of the electric guitar is easier on the hands of the player, it may actually encourage a begginer to learn the guitar more. Just my 2 cents..Peace.. 
Big misconception = marunong ka na sa pag naka power chords ka.
This is where I think you missed the music teacher's idea when he said to start out on acoustic guitars. although meron iba na kahit acoustic na nga ang gamit , naka-power chords pa din. And if you were starting out on learning the guitar why would you need to bend the strings? CHORDS, CHORDS, CHORDS!!!!
-- acoustic guitars have higher action -- kung di mo ipapa-adjust sa luthier.
eto pa isang misconception -- pag marunong ka mag "Lead" magaling ka.
try mo pumoste ng rhythm na masarap at pilit mong pupunuan yung kulang sa kanta para walang butas ang tunog niyo. Admittedly I am bad at this. and it's just recently that I found out how important rhythm playing is. kaya CHORDS, CHORDS, CHORDS!
