Buzz or Hum in Computer Speakers

I recently spoke with an audio engineer (my Dad, who has worked in radio for many years) about something that's been bugging me for many years: Why do almost all computer speakers have some sort of annoying buzz or hum?

I know it has to do with voltage differences, power, RF emissions, etc... but I wanted to know more about what I could try to do to reduce the level of the noise. I've tried things like plugging everything into one outlet/power strip, using a filtered power adapter, using a ground loop reduction magnet, etc., with varying degrees of success.

Fostex AR-4i iPhone 4/4S Stereo Audio Interface Review

Summary: 
Five stars for the capabilities, four for the fit and finish. It's a great tool, but not without a few rough edges. (See note about iPhone 4S compatibility).

[UPDATE on iPhone 4S compatibility: I've heard many reports of people having trouble with the AR-4i and the iPhone 4S; my own usage indicates that there is one quirk with this combo: the wireless signals on my phone go away while plugged into the AR-4i. Example recordings with various firmwares below:

Bose Companion 2 Series II Multimedia Computer Speaker System

Summary: 
Five stars for sound quality (especially considering the size of the speakers), but a 3 for the price (you still pay for the Bose® name).

For a very long time, I've used my computer, with a 24"+ display, as my TV, computer, DVD/Blu-Ray player, Xbox 360 setup, etc. Because of this, I had my 5.1 surround sound system, with some very nice speakers and a great sub, plugged into and surrounding my computer. It enveloped me in the most amazing aural arena I've ever experienced.

Sony MDR-XB40EX Extra Bass Earbuds

Summary: 
Solid performers for those wanting a bass-heavy aural experience and good isolation. The headphones can bring new life to some songs, but are often overbearing for those with sensitive ears.

Finding a good pair of headphones can be an lifelong vocation. In my short lifespan, I've probably given a good chance to about twelve different pairs, from earbuds to large cans used in professional/studio environments.

... or, Liturgical Music: Finding Hymnody to Enlighten the Mind and Lift the Soul

Having been a Seminarian for the Archdiocese of Saint Louis—an Archdiocese with great diversity in liturgical music, priestly ministry, and culture—I have had a great variety of liturgical experiences. Also, being a young adult with twenty-four years of musical listening habits under my belt, I've listened to a wide variety of genres, most especially alternative, classical, and pop music (with a bit of country music thrown in on the side). My most consistent favorite is soundtrack music (which can incorporate many of these styles in a single album).

Priestie Boyz - Lost in Ecstasy

A project on which I am proud to have worked is the recording and mastering of an album (pictured above) for a Seminarian rock band—I helped with everything besides the musical talent. (You can buy the album, Lost in Ecstasy, by the Priestie Boyz, on CDBaby or iTunes). I also had the privilege to work in radio engineering for five radio stations over the course of five years—two pop stations, one soft rock, and two AM/talk radio stations.

These experiences recently came to my mind simultaneously as I attended a youth-oriented Mass, at which many liturgical hymns (published in OCP) were sung with the accompaniment of two guitars, a drum set, and some percussion instruments.

In my analytical mind, I was using my mind's waveform analyzer (didn't know I had one of those until now!) to 'see' the music. What I saw made me think quite a bit about the different genres of music, and different purposes of music—especially liturgical music. In particular, I thought about the efficacy of different styles of music in worship, and how fitting (or unfitting) are different styles, especially for different audiences.
