    My friend complaint that his MacBook Air 13" 2011 does buzz a little bit though when blasting music at maximum volume. Additionally, it does not sound as loud as he expected. It seems that something blocks the internal speaker.

    I helped him check out, and this is what I have found out.

    In this forum, some people have said that it is owing to the backlit cover which blocks the sound. I do not have the 2010 Air model, nor does my friend, so I cannot confirm this story.

    I inspected his laptop for a while, and then when I removed his keyboard protector, it seems that the volume is 50% louder :D.

    And it even seems that the buzz effect reduces a lot though. You have to be really anal to detect the buzz effect. It is there (of course, it is just an built-in speaker), but it is really really hard to realise the buzz effect.

    I inspected further, and have found out that quality of sound maybe a key factor. When playing 320 kbps quality songs, it runs smoothly. With 128 kbps songs, it only buzzes here and there at around 70-80% volume, but then at 100%, the loud volume > effect :D.

    So the morals of the whole story are:
    1. Do not use a keyboard protector :D.
    2. Do not store cheap music in your laptop ;).

    On the fence
    320k songs are pretty big for something with such limited storage space. And yes, a keyboard protector will definitely muffle the sound on the MBAs and 13" MBP.

    So you mean the lessons are:
    1. Store 320 kbps songs on external hdd or online (such as iCloud)
    2. Do not store 320 kbps songs
    3. Do not buy MacBook Air

    Depending on the loudness of the source music, you shouldn't be running your built in speakers at 100% volume anyway. For "quiet" type music like classical, then running at 100% should be acceptable. But most modern music these days have been increased in loudness several fold. You can damage or blow your speakers by running them at 100%.

    If you want your music loud, you should use external speakers, or plug in some headphones.
