What causes humming in speakers?

Though some noise is inherent in the audio signal (tape hiss, amp gain, etc.), speaker hum and hiss generally come from poor wiring, ground loops or other electromagnetic interferences (AC line hum; RF interference, and USB and PC noise). To rid of the noise, we must rid of the interference.

How do I determine the age of my Bose Wave Radio?

if the problem persists at that point, it’s hardware related, and would indeed require repairs to correct Nathan : For a unit this age, it is probably not worth the investment, it is rare for any electronics device to last this long, as the capacitors inside will degrade and fail just from age. Nathan :

What should I do if my boiler makes a whooshing noise?

A boiler that begins to make loud ‘whooshing’ noises and vibrate excessively can be very scary, however the actual cause may be quite simple to diagnose and fix. Whilst there is no immediate danger, allowing the problem to persist can cause further damage so immediate action should be taken. 1. Check the air intake/flue

How can 30 year old receivers sound better than new ones?

The receiver engineers have to devote the lion’s share of their design skills and budget to making the features work.

How much do I get for a Bose Wave Radio?

You may get some value out of the existing unit by selling it (ebay, craigslist) as well, even if just from someone looking for parts. In non working condition, I’d expect you could get $25-50 for it, by someone looking for parts or to restore it themselves.

How long did it take to develop Bose Wave Radio?

The number of years that Bose claims it took to research and develop the Wave audio system, according to one of its user manuals. The work on the waveguide technology earned Dr. Bose and Dr. Short numerous awards. The Bose Wave Music System III, shown with a CD changer. More recent models support Bluetooth. (Handout)

What did Bose do with his research on sound?

That led Bose, who became an MIT professor or engineering, to dive into audio research on how to maximize the sound that could come out of a pair of speakers. Eventually, his research led him to make speakers that worked much the same way as actual music being played in a concert hall did—with the sound waves reverberating off the walls.

What are the symptoms of a Bose Wave Radio?
