==Explanation==
This comic is about experiencing a high pitched hum in an empty room. It refers to the title text in comic [[597: Addiction]]. An "empty-room hum" is a high pitched buzzing noise, which [http://wiki.answers.com/Q/What_is_the_high_pitched_humming_sound_often_heard_in_an_otherwise_empty_and_silent_room it is suggested] results from the brain increasing its sensitivity to noises.

Sometimes not everyone can hear "empty-room hum"; however, those who can hear it usually find it immensely annoying. If you do hear the noise, you would like to locate '''The Source''' – hence the title of the comic. Hopefully when you find the source, you can do something about it. Or if you don't find it, you can at least be at ease knowing that others experience the empty-room hum, it having been referenced in two xkcd comics now and [http://wiki.answers.com/Q/What_is_the_high_pitched_humming_sound_often_heard_in_an_otherwise_empty_and_silent_room elsewhere] on the internet.

This comic alludes to the perspective of an outside observer who doesn't hear the hum but is watching someone who can hear it: because the sound isn't written out in text, the comic reader at first is confused by Cueball's inexplicable searching.

In the first two frames of the comic we see [[Cueball]] trying to locate the direction of the sound, by standing in the middle of the room, turning his head from one to the other side. Finally he walks down a flight of stairs (probably to the basement) and here he locates the source: A machine whose only function is to generate a high pitched hum. The title text asks why on Earth they had such a machine in the first place, which is somewhat difficult to explain and likely the crux of the title text's joke.

Luckily it was thus easy for Cueball to get rid of this sound at the source. But in real life most electronics generate hums and cannot reasonably be turned off without losing functionality. For instance fluorescent lights, phone chargers and computer modems are common culprits, refrigerators and washing machines less commonly. It could also come from outside the house, in which case it will be much harder either to locate the source or to do anything about it. Power lines and transformers are common outside sources.

There do, however, exist devices that are meant to create a high pitched hum, that people might wish to install in their house. These will be humming in the {{w|ultrasound|ultrasonic}} regions, although cheap versions can often be heard by young people. They are typically used for {{w|Electronic_pest_control#Ultrasonic|electronic pest control}}, while slightly lower frequencies which can typically be heard only by young people are sometimes used to {{w|The Mosquito|repel children}}. It is possible that someone tried to get rid of Cueball.

There do exist {{w|white noise}} generators (which make equal volume noise on every frequency) and {{w|pink noise}} generators (which make noise that sounds equally loud to the human ear at every frequency) which are used to test recording studios to see if they have good sound quality. It seems unlikely that the device is one of these, as it seems to be designed to generate a high-pitched hum: pink/white noises are categorically and perceptually different from a hum.

The empty white room is also likely a reference to a scene from [https://en.wikipedia.org/wiki/The_Matrix_Reloaded The Matrix Reloaded] in which Neo searches for "The Source," though this could just be a coincidence.

Mildly interesting to note that the ordering of most of the checkbox/radiobutton lists randomise each time the survery is loaded. Also, there is at least one other comic where Randall comments about not having figured out HTML imagemaps. Anyone remember which? --[[User:Pudder|Pudder]] ([[User talk:Pudder|talk]]) 10:52, 2 September 2015 (UTC)
:It was in one of his "under the logo" news bars, about him starting What If, iirc --[[User:Aescula|Aescula]] ([[User talk:Aescula|talk]]) 11:28, 2 September 2015 (UTC)
I wonder how many people, on reading 'Type "cat" here:', typed '"cat" here:'? I know I did... [[Special:Contributions/141.101.98.214|141.101.98.214]] 11:58, 2 September 2015 (UTC)

Not sure if it was just me, but the comic wasn't a link at all! The cursor changed into a No cursor for me everytime I mouseover'd the comic. I went to survey using the "Bonus Link!" below the comic page. [[User:Brilliantnut|Brilliantnut]] ([[User talk:Brilliantnut|talk]]) 12:01, 2 September 2015 (UTC)
:Never mind, this was probably due to the WebComics reader extension that I have in my browser. [[User:Brilliantnut|Brilliantnut]] ([[User talk:Brilliantnut|talk]]) 12:03, 2 September 2015 (UTC)
From hearing people on reddit comment about not being able to completely fill the text box (not just the visual box) with the error "Answer too long", it's caused by a 10k character limit. Presumably by Google Docs. [[Special:Contributions/108.162.249.192|108.162.249.192]] 13:18, 2 September 2015 (UTC)

I assume that this is made, at least in part, in reference to the just-made OnePlus infodump and their upcoming OnePlus 2 smartphone. [[Special:Contributions/162.158.2.188|162.158.2.188]]

"Ear screen" may refer to a different meaning of "screen" - a device that protects you from something, as in "sun screen". In this case, the "ear screen" would block the sound of the phone's speakers, making it useless (at least for telephony). 08:02, 10 July 2015 (UTC)~~ [[User:thepike|thepike]]

Doesn't running natively just mean that it runs apps natively instead of emulating them or something. Which would be a pointless marketing term OR it implys that the phone itself or the person inside runs.[[Special:Contributions/108.162.249.192|108.162.249.192]] 10:53, 10 July 2015 (UTC)
