What HellBlocker Is Designed to Reduce
HellBlocker works best with steady background noise, such as:
- Airplane engines
- Fans
- Road noise
- Air conditioning
Sudden or changing sounds may still be audible, including:
- Conversations
- Alarms
- Keyboard clicks
Hearing some sudden sounds does not necessarily mean that HellBlocker is malfunctioning.
Frequently Asked Questions
Why can I still hear people talking?
HellBlocker is designed primarily to reduce steady background noise. Changing sounds such as speech may still pass through.
Is it normal to hear keyboard clicks or alarms?
Yes. Sudden sounds such as keyboard clicks and alarms may remain audible even when HellBlocker is enabled.
Why does the noise occur only when HellBlocker is on?
This indicates that the issue may be related to HellBlocker. Update the firmware, turn the feature off and back on while music is playing, and compare the results across different connections and devices.
