Waking up on time can be tough, especially if you are a heavy sleeper or keep hitting the snooze button. Many people rely on alarm clocks to make sure they start their day on schedule. Among the many options available, the Sharp Big Bang Alarm Clock stands out for its loud sounds and unique alarm features. But what exactly are the sounds included in this popular device? And how do they compare to other alarm clocks on the market? If you are considering buying the Sharp Big Bang or just want to understand what makes its alarms so effective, this article will walk you through everything you need to know.
Overview Of The Sharp Big Bang Alarm Clock
The Sharp Big Bang Alarm Clock is well known for its extra-loud alarm and simple design. This clock is targeted at people who have trouble waking up with standard alarm clocks. It is especially popular with deep sleepers, students, and those with mild hearing loss. The main selling point is the variety of sounds and the ability to choose the best one for your personal wake-up needs.
This clock is not a smart device. You will not find Bluetooth or app connectivity. Instead, it focuses on reliability, simplicity, and, most importantly, alarm sound options. Understanding the range and type of sounds it offers will help you decide if it’s the right alarm clock for you.
What Sounds Are Included In The Sharp Big Bang Alarm Clock?
Sharp designed the Big Bang Alarm Clock with a variety of alarm sounds to suit different preferences and needs. Here are the main types of sounds you will find:
1. Traditional Buzzer
The classic buzzer is a familiar, loud ringing sound, similar to what you find in most standard alarm clocks. This buzzer is designed to be sharp and persistent, making it hard to ignore. Its volume is notably higher than most digital alarm clocks, reaching up to 113 decibels in some models. For comparison, this is about as loud as a jackhammer from a short distance.
2. Pulsating Beep
The pulsating beep is a more modern sound choice. Instead of a steady ring, this alarm emits beeps in a rhythm that increases in speed and intensity. This changing pattern can be especially effective for people who have learned to tune out a steady sound. The increasing tempo tricks your brain into paying attention.
3. Bell Sound
Some Sharp Big Bang models offer a bell alarm, which mimics the ringing of an old-fashioned school bell. This metallic, reverberating sound has a nostalgic feel and is very effective at waking most people. The bell is usually set at a high volume, adding to its ability to jolt sleepers awake.
4. Siren Sound
A powerful siren alarm is included in certain versions. This sound is similar to a fire or emergency alarm, delivering a loud, urgent noise that demands immediate attention. The siren is especially useful for extremely heavy sleepers or people with mild hearing difficulties. However, some users find this option too intense for daily use.
5. Custom Sound Sequences
Some enhanced models of the Big Bang allow you to select a custom sound sequence, where the alarm cycles through multiple sounds in one alarm session. For example, it may start with a beep, switch to a bell, then finish with a buzzer. This variety can help prevent you from getting used to a single sound and sleeping through it.
6. Vibrating Alarm Option
While not a sound, some Sharp Big Bang Alarm Clocks include a vibration feature. This is especially helpful for those who are hearing impaired or do not want to disturb a partner. The vibration is strong enough to shake a nightstand or pillow.
Comparing The Sound Options
Here is a quick comparison of the core sound features in popular Sharp Big Bang Alarm Clock models:
| Model | Buzzer | Pulsating Beep | Bell | Siren | Custom Sequence | Vibration | Max Volume (dB) |
|---|---|---|---|---|---|---|---|
| Big Bang Classic | Yes | No | Yes | No | No | No | 108 |
| Big Bang Deluxe | Yes | Yes | Yes | Yes | Yes | Yes | 113 |
| Big Bang Lite | Yes | Yes | No | No | No | No | 105 |

How The Sharp Big Bang Sounds Compare To Other Alarm Clocks
Sharp’s Big Bang clocks are not the only loud alarm clocks on the market, but their focus on variety and intensity sets them apart. Here’s how they compare with other well-known brands:
| Brand | Loudest Alarm (dB) | Number of Sound Options | Vibration Feature | Customizable Alarms |
|---|---|---|---|---|
| Sharp Big Bang | 113 | Up to 5 | Yes (select models) | Yes (Deluxe) |
| Sonic Bomb | 113 | 3 | Yes | No |
| Philips Wake-Up Light | 80 | 7 (nature sounds) | No | No |
| iHome Bluetooth Clock | 90 | Unlimited (music) | No | Yes |
As you can see, while some clocks offer more “pleasant” or nature-inspired sounds, the Sharp Big Bang focuses on loud, attention-grabbing alarms. This makes it a favorite for people who struggle to wake up with soft or soothing noises.
Why Sound Variety Matters For Waking Up
Most people think all alarm clocks work the same. But the type of sound and its pattern can make a big difference in how effective the alarm is. Here’s why:
- Habit and Adaptation: If your brain gets used to a single sound, you might start sleeping through it. Changing the alarm sound regularly can help keep your mind alert.
- Personal Preference: Some people wake up better to a sharp beep, while others respond more to a ringing bell or a siren. Having choices allows you to pick what works best for you.
- Hearing Differences: Not everyone hears the same frequencies well. Loud, high-pitched sounds may work for some, while lower or more complex sounds work for others.
- Shared Bedrooms: A variety of sounds—including vibration—means you can choose a wake-up method that does not disturb your partner.
A non-obvious insight: Some users report that alternating the alarm sound every few days helps prevent “alarm fatigue.” This is when your brain starts to ignore a familiar wake-up sound. By using the Sharp Big Bang’s different options, you can keep your morning routine fresh and effective.

Tips For Choosing The Best Sound On Your Sharp Big Bang Alarm Clock
Selecting the right alarm sound is not just about volume. Here are a few tips to help you get the most from your Big Bang clock:
- Test Each Sound: Try each alarm option for a few days to see which wakes you up fastest and leaves you feeling most alert.
- Adjust the Volume: Start at a lower volume and increase it only if you find you are sleeping through the alarm. Extremely loud alarms can be jarring and may cause stress if not needed.
- Consider Your Room Setup: Hard surfaces reflect sound, making alarms seem louder. If your clock is near a wall or on a wooden nightstand, the sound may be amplified.
- Use the Vibration for Shared Spaces: If you do not want to wake your partner, try the vibration feature or place the clock under your pillow.
- Change the Alarm Regularly: To avoid getting used to one sound, switch it up every week. This keeps your brain responsive.
Another practical tip: If you find yourself turning off the alarm and falling back asleep, try placing the clock across the room. The loud sound will force you out of bed to turn it off, making it harder to fall back asleep.
Features Beyond The Alarm Sounds
While the main topic is the alarm sounds, it’s helpful to know about other features the Sharp Big Bang offers. These include:
- Large, easy-to-read display: Ideal for people who do not want to squint to see the time.
- Simple controls: Buttons are well-labeled and easy to use, even when half-awake.
- Battery backup: Ensures the alarm works even if the power goes out.
- Snooze function: Offers a short delay for those who need a few extra minutes.
Some models also include nightlight features or adjustable brightness. These extras do not affect the alarm sounds but can improve your overall experience with the clock.
Real User Experiences: What People Say About The Alarm Sounds
People who use the Sharp Big Bang Alarm Clock often mention how effective the sounds are at waking them up. Here are some common comments:
- “I used to sleep through three alarms. The buzzer on this clock gets me up every time.”
- “The siren is almost too much, but on days when I have an early flight, it’s perfect.”
- “I like being able to switch between the bell and beep, so I do not get used to one sound.”
- “The vibration is strong enough to wake me up but does not disturb my partner.”
A less obvious insight: Some users with partial hearing loss find that the combination of loud sound and vibration is more effective than any alarm they have used before.
Who Should Buy The Sharp Big Bang Alarm Clock?
The Sharp Big Bang is best for:
- Heavy sleepers who need a loud, persistent alarm.
- People with mild hearing loss who struggle with quiet alarms.
- Students and professionals who cannot afford to oversleep.
- Anyone sharing a room who wants a vibration option.
- People who dislike smartphone alarms or want a device with no distractions.
It is less suitable for those who prefer gentle, nature-inspired wake-up sounds or want a smart alarm with app integration.
