The Sharp Big Bang Clock is famous among heavy sleepers and anyone who struggles to wake up in the morning. With its bold design and strong alarms, it stands out in a crowded market of digital alarm clocks. But one question often comes up: How many alarm sounds does the Sharp Big Bang Clock have? This article will answer that in detail, explore the differences between each sound, and give you all the facts you need to know before buying or using this unique clock.
What Makes The Sharp Big Bang Clock Special?
Many people search for alarm clocks that do more than just beep. The Sharp Big Bang Clock is designed for those who need something extra to start their day. What sets it apart is not just its appearance, but its features, especially the variety and intensity of its alarm sounds.
Why Alarm Sound Variety Matters
Not everyone responds to the same alarm. Some people wake up to a gentle tone, while others need a loud, sudden noise. The number of alarm sounds and their quality can make the difference between waking up refreshed or oversleeping.
How Many Alarm Sounds Does The Sharp Big Bang Clock Have?
The Sharp Big Bang Clock offers four unique alarm sounds. Each one is designed with a purpose, so users can select the sound that best fits their sleep habits or preferences.
The Four Alarm Sounds Explained
Here’s a closer look at what you get:
- Classic Beep: The traditional electronic beep, sharp and consistent.
- Loud Buzzer: A more intense, mechanical buzzing sound.
- Ringing Bell: Mimics the old-fashioned twin-bell alarm, with a metallic ring.
- Big Bang Blast: A high-volume, rapid pulsing tone, unique to this model.
Each sound is distinct in volume, rhythm, and tone. The clock’s manual and packaging clearly state that four alarm sounds are included.
Non-obvious Insight 1
Some users think the clock has more than four sounds because each alarm can be set with different volume levels. However, while you can adjust the volume, there are only four basic sound types.
Non-obvious Insight 2
The Big Bang Blast is not just a gimmick—it’s specifically designed for deep sleepers. Its frequency and pattern have been tested to break through heavy sleep cycles more effectively than standard beeps.
How Do The Alarm Sounds Compare?
Let’s compare the four sounds to help you decide which one might work best for you.
| Alarm Sound | Volume Range | Best For | Wake-Up Style |
|---|---|---|---|
| Classic Beep | Medium–High | Light Sleepers | Gradual |
| Loud Buzzer | High | Heavy Sleepers | Sudden |
| Ringing Bell | Medium | All Users | Traditional |
| Big Bang Blast | Very High | Deep Sleepers | Intense |
How Loud Is The Sharp Big Bang Clock?
Volume matters as much as the number of sounds. The maximum volume of the Big Bang Blast is about 113 decibels—comparable to a rock concert or a chainsaw. The other sounds range from 70 to 100 decibels. This makes the clock one of the loudest on the market.
How To Select And Set The Alarm Sounds
Choosing your alarm sound is easy with the Sharp Big Bang Clock. Here’s a step-by-step guide to setting the alarm sound:
- Press the “Alarm Set” button until the alarm sound option appears.
- Use the “Sound Select” button to cycle through the four sounds.
- Press “Set” again to confirm your choice.
- Adjust the volume with the “Volume” dial.
- Set the alarm time as usual.
Many users appreciate the simple interface, which makes it easy to change alarm sounds even when you’re half asleep.
Tips For Choosing The Right Sound
- If you are a light sleeper, try the Classic Beep or Ringing Bell.
- For deep sleepers, the Loud Buzzer or Big Bang Blast is more effective.
- If you have roommates or share a wall, consider a lower volume at first.
- Switch up your alarm sound every few weeks to prevent your brain from getting used to one pattern (a common reason people oversleep).

How Does It Compare To Other Popular Alarm Clocks?
To understand the uniqueness of the Sharp Big Bang Clock, let’s compare its alarm sound options with other popular models.
| Model | Number of Sounds | Loudest Sound (dB) | Special Feature |
|---|---|---|---|
| Sharp Big Bang Clock | 4 | 113 | Big Bang Blast |
| Sonic Bomb SBB500SS | 3 | 113 | Bed Shaker |
| Philips SmartSleep | 7 | 87 | Gentle Light Wake-up |
| RCA RCD30 | 2 | 80 | Simple Beep |
As you can see, while some clocks offer more sounds, the Sharp Big Bang Clock focuses on fewer, but more effective, loud options. It’s ideal for those who need sound power over variety.
Who Should Choose The Sharp Big Bang Clock?
The Sharp Big Bang Clock isn’t for everyone. It’s best for people who:
- Struggle to wake up with regular alarms
- Have hearing difficulties
- Need a reliable backup alarm for important events
- Prefer easy-to-use controls
If you are a light sleeper or sensitive to noise, this clock may be too intense. But for college students, shift workers, or anyone with a heavy sleep pattern, it’s a practical choice.
Examples And Real-life Use
Many college students living in dorms use the Big Bang Blast to avoid missing early classes. Truck drivers and shift workers also rely on the Loud Buzzer for naps during odd hours.
Pro Tip
The clock can double as an emergency alert device for people with hearing loss, especially when paired with a bed shaker (sold separately).

Other Features That Matter
While this article is focused on the number of alarm sounds, it’s worth noting some other features that make the Sharp Big Bang Clock user-friendly:
- Large LED Display: Easy to see, even in the dark.
- Battery Backup: Keeps time and alarm settings during power outages.
- Snooze Button: Standard 9-minute snooze, but the sound remains loud.
- Simple Controls: No complicated menus or touch screens.
These features support the clock’s main purpose: waking you up, no matter what.
Common Mistakes When Using The Alarm Sounds
- Not testing each sound before choosing one. Some users pick the default, which might not be the most effective.
- Setting the volume too low. If you live in a noisy area, the alarm may blend into background sounds.
- Forgetting to set the alarm for AM/PM. The clock uses a 12-hour format, so it’s easy to confuse morning and evening times.
- Relying on one sound for too long. Your brain can adapt, making the alarm less effective over time.
- Ignoring the snooze feature. If you need to wake up at a specific time, using the snooze too often can defeat the purpose of a loud alarm.

What Users Say About The Alarm Sounds
Most users agree that the Big Bang Blast is the most effective sound for heavy sleepers. Positive reviews often mention:
- “I haven’t overslept since I bought this clock.”
- “The Big Bang Blast is no joke—it wakes me up every time.”
- “Easy to switch alarm sounds, very loud.”
A few users find the loudest settings too intense, but this is usually a sign to try the lower-volume sounds or adjust the settings.
How To Maintain The Alarm Sound Quality
To keep your Sharp Big Bang Clock working well:
- Clean the speaker vents regularly, as dust can muffle the sounds.
- Check the battery backup every 6 months.
- Keep the clock away from water and extreme temperatures.
If you notice the alarm getting quieter, it might be time to replace the clock or check for blockages.
Are There Custom Alarm Sounds?
Unlike some smart clocks, the Sharp Big Bang Clock does not support custom alarm sounds or Bluetooth streaming. It’s designed for reliability and simplicity, not for playing music. If you want custom ringtones, you may need a different model.
Where To Buy And Price Range
The Sharp Big Bang Clock is available at most major retailers, both online and in stores. Prices typically range from $24.99 to $39.99, depending on features and store promotions. For more technical details, you can check the Alarm clock Wikipedia page.
