Waking up on time can be a daily struggle. Many alarm clocks are easy to ignore or snooze. The Sharp Big Bang Alarm Clock aims to solve this problem with a unique approach. It’s designed not just to wake you, but to make sure you get out of bed. But how does it actually work, and is it effective? In this article, you’ll get a clear, detailed look at what makes the Sharp Big Bang Alarm Clock special, how its features function, and what sets it apart from regular alarm clocks.
What Is The Sharp Big Bang Alarm Clock?
The Sharp Big Bang Alarm Clock is a high-volume, extra-loud alarm clock. It’s built for deep sleepers, people with hearing difficulties, or anyone who struggles to wake up with a standard alarm. Unlike most clocks, the Big Bang uses a combination of loud sound, vibration, and flashing lights to grab your attention.
This clock has become popular in homes, dorms, and even among shift workers. Its reputation comes from its power and unique features. Let’s explore how it works, starting with the design and moving through its main functions.
Key Features And How They Work
The Big Bang Alarm Clock is not just about being loud. It’s a well-thought-out device with several features that work together to guarantee you wake up.
1. Super Loud Alarm
The standout feature is the 113-decibel alarm. To give you a sense of how loud that is, normal conversation is about 60 decibels, a vacuum cleaner is around 70, and a chainsaw is roughly 110 decibels. The Sharp Big Bang’s alarm is almost as loud as a live rock concert.
- How it works: When the alarm triggers, the clock emits a sharp, piercing sound. The volume is adjustable, so you can set it based on your needs. At the highest setting, it’s nearly impossible to sleep through.
2. Bed Shaker Vibration
Many people can ignore even loud alarms if they’re deep sleepers. The Big Bang includes a bed shaker—a small device connected by wire to the clock. You place this shaker under your pillow or mattress.
- How it works: When the alarm goes off, the shaker vibrates strongly. This physical sensation is hard to ignore, especially for people who have trouble hearing or sleep very deeply.
3. Flashing Strobe Lights
Some people are sensitive to light rather than sound or touch. The Big Bang has bright strobe lights on the front of the clock.
- How it works: When the alarm activates, these lights flash in a pattern. The intense light can wake people who are heavy sleepers or have hearing loss.
4. Multiple Alarm Modes
You can use sound, vibration, and lights together or separately. This flexibility means you can customize the wake-up experience.
- Practical example: If you share a room, you might use just the shaker to avoid disturbing others. Or, if you need extra help, use all three modes at once.
5. Large, Easy-to-read Display
The clock face features big digits with a clear backlight. This is helpful for people with vision problems or for checking the time at night.
- Non-obvious insight: The display is designed to be visible from across the room, even in low light.
6. Simple Controls
All settings are adjusted with large, labeled buttons. There’s no confusing menu system or hidden functions.
- User experience tip: Many people choose this clock because it doesn’t require a complicated setup or a smartphone app.
How Does The Sharp Big Bang Alarm Clock Wake You Up?
The Big Bang Alarm Clock uses a multi-sensory approach. Here’s what happens when your alarm time arrives:
- The alarm emits a very loud sound—enough to wake most people instantly.
- At the same time (if set), the bed shaker vibrates under your pillow or mattress.
- The strobe lights flash, filling your room with bursts of brightness.
- If you don’t turn off the alarm, it continues until you respond.
This combination makes it much harder to sleep through your alarm. It’s especially effective for people with hearing loss, deep sleepers, or those who have trouble waking up with traditional alarms.
Step-by-step Setup Guide
Setting up the Sharp Big Bang Alarm Clock is straightforward, but a few tips can help you get the most from it.
Unboxing And Placement
- Remove the clock and the bed shaker from the box.
- Plug the shaker into the labeled port on the clock.
- Place the clock on a stable surface near your bed.
- Tuck the bed shaker under your pillow or mattress.
Setting The Time And Alarm
- Use the “Time Set” button to adjust the current time. Hold it down and use the up/down buttons to set hours and minutes.
- Press the “Alarm Set” button, then adjust to your desired wake-up time.
- Choose your alarm mode: Sound, shaker, light, or any combination.
- Adjust the volume wheel to your preferred loudness.
Testing The Alarm
- Always test the alarm before your first night.
- Press the “Test” button (if available) to make sure the sound, shaker, and lights are working.
Using The Snooze And Off Functions
- The snooze button delays the alarm for a few minutes (usually 9 minutes by default).
- The off button stops the alarm completely until the next scheduled time.

Real-life Example: Who Uses The Big Bang Alarm Clock?
Let’s look at a practical example. Sarah is a college student who sleeps very deeply. She often misses classes because regular alarms don’t wake her. After trying the Sharp Big Bang, she uses the maximum sound and the bed shaker together.
Now, she wakes up on time every morning—even when she’s exhausted.
Another example is Mark, who shares a room with his partner. He sets only the bed shaker, so he wakes up without disturbing his partner. The flexibility of the alarm modes is a major plus in situations like this.
How Does It Compare To Other Alarm Clocks?
A comparison helps clarify where the Big Bang stands out. Here’s a look at how it matches up against typical loud and vibrating alarm clocks:
| Feature | Sharp Big Bang | Standard Loud Alarm | Vibrating Alarm |
|---|---|---|---|
| Max Volume | 113 dB | 80-90 dB | 60-80 dB |
| Vibration | Included | Rarely | Yes |
| Flashing Light | Yes | No | No |
| Alarm Modes | Customizable | Sound only | Sound + Vibration |
| Display | Large, Backlit | Standard | Small |
The Big Bang stands out for its triple-alert system and extreme volume. Most alarms do not offer all three wake-up methods.

Common Mistakes And How To Avoid Them
Many first-time users make simple mistakes with the Big Bang Alarm Clock. Here are two common issues and how to solve them:
- Not placing the bed shaker correctly: If you just leave it on the bedside table, you won’t feel the vibration. For the best effect, slide it directly under your pillow or the corner of your mattress.
- Setting the volume too high at first: The highest setting is very loud. Try a medium setting first, then increase if needed. This protects your ears and prevents startling you or others.
Another tip: Plug the clock into a stable power source. If power is lost, the backup battery will keep your settings, but the alarm won’t be as loud.
Who Is The Big Bang Alarm Clock Best For?
This clock isn’t for everyone. It’s designed for:
- Deep sleepers who ignore typical alarms.
- People with hearing loss who need vibration or light.
- Shift workers who sleep during the day and need strong cues.
- Roommates or couples where only one person needs a strong alarm.
If you’re a light sleeper, the lowest sound setting or just the shaker may be enough. For most people, at least two alert methods work best.
The Science Behind Waking Up
Why are multiple alert methods so effective? Waking up is a biological process. When you’re in deep sleep, your brain blocks out normal sounds. But a combination of loud noise, vibration, and bright light triggers different senses. This increases the chance you’ll wake up—especially if you’re very tired or sleep through standard alarms.
Research shows that multi-sensory alarms are much more effective than single-sense ones. This is why the Big Bang’s design is supported by science.
Practical Buying Guide: What To Check Before Purchasing
If you’re considering the Big Bang, check these points:
- Alarm volume: Make sure you can adjust it to your needs.
- Bed shaker quality: Some cheap models have weak vibration. The Big Bang’s shaker is known for being strong.
- Display size: If you have vision problems, large digits are helpful.
- Power backup: A battery backup is important so you don’t lose settings during outages.
Here’s a quick comparison of the Sharp Big Bang with a popular competitor:
| Model | Alarm Volume (max) | Bed Shaker | Display Size | Strobe Light | Price Range |
|---|---|---|---|---|---|
| Sharp Big Bang | 113 dB | Yes | Large | Yes | $40-$60 |
| Sonic Bomb | 113 dB | Yes | Medium | Yes | $35-$55 |
Both clocks are powerful, but the Big Bang is praised for its simple controls and large display.
Maintenance And Care Tips
To keep your alarm clock working well:
- Clean the display with a soft, dry cloth.
- Don’t use water or sprays on the clock.
- Check the backup battery every six months.
- Coil the bed shaker cord neatly to avoid damage.
- Avoid placing the clock in direct sunlight, which can fade the numbers.
These steps help your clock last longer and stay reliable.
