On this page, issues related to amplified sound are explained.
Problems
First, let's take a look at the problems that commonly occur.
Normal
Listen to how each problem makes this sound worse, assuming this is normal sound.
Insufficient Volum
This is a situation where the volume is low compared to the surrounding noise and it is difficult to hear.
|
Clipping
The sound is cracked and cannot be heard clearly. This sound gives a crude impression.
|
>>> Cause & Solution
High Frequency Less
The high frequency volume is insufficient.
Even if the overall volume is sufficient, the sound is difficult to hear. |
Reverberation
When there is reverberation due to the influence of the building.
This may be good for music, but it's bad for speeches and announcements because it makes them difficult to hear. |
Reverberation + High Freqency Less
When the above two things overlap,
it becomes really difficult to hear.
it becomes really difficult to hear.
>>> Cause & Solution
Feedback
A phenomenon in which a loud and strong sound is emitted from a speaker.
Feedback can also destroy all equipment and audience's ears.
