The Sonic Bomb also has three red LEDs that can be made to flash and comes with a vibrating pad you can place under your pillow to shake you awake.

Again, not terribly creative, and also unnecessary in the face of its ear-splitting sonic blast. If you think you need something this strong, hit up Hammacher Schlemmer and pay $35 (USD). Or go see a specialist.

I have been in cars before with powerful subs that were loud enough to hurt my ears and make the windows bulge in the car, but this stereo system takes it to a new level. To show how much air the four subs in their enclosure displace, the guy took a phone book and crammed it into the giant port the air comes out of. Watch the video to see what happens – jump to about 2:45 for the good part.

Suffice it to say that guys won’t want to get their family jewels anywhere close to that port or they will face an air-powered rack-o-rama.

This extra-loud alarm clock gets its power from a couple of 140-decibel electric horns. A relay, a 12-volt laptop power supply and a whiff of solder later, and this cheap alarm clock was transformed into the most ear-shattering alarm clock you’ll ever hear.

Here, have a listen:

As an added bonus, it’s guaranteed to wake all members of your immediate family and each neighbor on your block.

Still, if you have more money than god, you might want to check out Transmission Audio’s Ultimate, a gigantic speaker that houses an array of seven-foot tall panels loaded with an ungodly amount of speakers. Measuring in at nearly 19 feet wide, and loaded up with forty 15-inch subwoofers, twenty-four 8-inch woofers, and a boatload of 2-inch and 1-inch ribbon tweeters, it’s best to think of The Ultimate like a meta-speaker, rather than a single entity. That said, each one is still a designed for mono sound – so if you’re looking for stereo, be prepared to shell out a cool $2 million bones. And for a full 7.1 sound system, you’ll be looking at more than the GNP of some third-world countries.

Frequency response for the Ultimate is rated at an unreal 15Hz to 50kHz, and each system comes with a set of six 500-watt-per-channel dual mono amps, capable of cranking out a total of 6,000 ear-shattering watts of power. At full blast, the speakers can pump out an astounding 146dB SPL. That’s somewhere between “HUMAN BODY FEELS AS IF SOMEONE JUST FOOTBALL TACKLED YOUR CHEST” and “FORMULA 1 RACE CAR, 700 HORSEPOWER” on the decibel chart. Now that’s what I call a sonic boom. Just don’t come crying to me when your neighbors call the cops.

The Screaming Meanie 220 portable alarm clock offers three settings: normal (75dB), loud (95dB), and earsplitting (120dB). To put those decibel levels in perspective, the lowest setting is as loud as a vacuum cleaner. If you happen to crank it up to the highest level, you’re somewhere between sitting in the front row of a rock concert and sitting in front of a jet engine. And just to make sure you don’t oversleep, there’s 5 and 10 minute “pre-alarms” which remind you that the REAL alarm is coming. While you can turn off the pre-alarm with a single button press, you need to press three buttons at once to shut off the main alarm.

While they’re certainly not pretty to look at, I can pretty much assure you that you won’t sleep past the buzzer with one of these things. So if you’re ready to be jarred awake, you can find one at the Perfect Present for about $36 (including shipping).

The next time a car tries drive in the bike lane, hit ‘em with the 115 decibel blast of the Thunder Horn. To put it in perspective, that’s about as loud as standing in the front row of a Metallica concert. The $12 horn can crank out an earsplitting alert that should wake up even the laziest of drivers and peds.

This manufacturer’s warning pretty much sums it up: “Do not use within 50cm (18 inches) of anyone(s) ears to avoid damage.”

For those of you not familiar with the Decibel Scale, that’s somewhere between “Front Rows at Rock Concert” and “Threshold of Pain.” Unfortunately, this video of the phone in action doesn’t really capture just how load 120dB is.

Featuring an array of five speakers, and “dynamic 3D sound,” the QKphone 911 suffers from a serious identity crisis. While it’s loaded with all the typical business applications of a Windows Mobile Smartphone, it’s also got a bunch of multimedia capabilities, including a weird media player with a dancing girl on it.

I can only imagine how obnoxious those horrible Crazy Frog ringtones would be on this device.

According to this post over at Xbox Scene, some consoles manufactured after November 2006 appear to be getting a new BenQ DVD Drive (the VAD6038), which is supposedly much quieter than earlier drives. There’s also some conjecture that the new drive reads a bit more quickly than the previous drives.

Now if only Microsoft would offer an upgrade for all of us suckers who picked up a 360 in the first year it came out.

Coined the “Mosquito Ultrasonic Teenage Deterrent,” the device emits annoying tones that can only be heard by those aged 20 and younger. The device is based on the same principal of the silly “mosquito” cell phone ringtones that only teens should be able to hear (I’m 39 and I can hear those ringtones, so go figure). So if you’ve got a gaggle of rugrats hanging out in front of your home or business, or just want to wreak havoc at the local shopping mall, you might want to pick one of these up.

To startle your unsuspecting victim, simple pull the pin and lob your grenade in their general direction. The Sonic Grenade lets out an ear-shattering sound that should scare (and annoy) the bejesus out of just about anyone who’s not legally deaf. As an added bonus, your unknowing victim cannot shut off the grenade without the pin. It’s just $13.95 from Firebox.com.
