What is DB trực tuyến?
What is DB trực tuyến?
The term DB trực tuyến refers to online decibel meters—tools that allow users to measure sound levels directly from their browser or mobile device using the device’s built-in microphone. These tools provide readings in decibels (dB), which is the standard unit used to measure the intensity of sound.
Unlike traditional sound meters that require physical devices, DB trực tuyến solutions work without additional hardware, making them an ideal option for quick, accessible noise assessments anytime, anywhere.

Common dB ranges and what they mean
Common dB ranges and what they mean
Understanding dB levels can help you assess whether a noise is safe or harmful. Here’s a handy reference table:
| Sound Source | Approx. dB Level | Risk Level |
|---|---|---|
| Whisper | 30 dB | Safe |
| Normal conversation | 60 dB | Safe |
| Traffic noise | 85 dB | Potentially harmful |
| Motorcycle engine | 95 dB | Harmful over time |
| Rock concert | 110-120 dB | Dangerous |
| Jet takeoff (close) | 130+ dB | Extremely dangerous |
According to health experts, prolonged exposure to sounds above 85 dB can lead to permanent hearing loss. That’s why it’s important to use tools like DB trực tuyến to monitor your environment.
When should you be concerned about noise levels?
When should you be concerned about noise levels?
Here are a few scenarios where monitoring sound levels is especially important:
