It's a common problem with flatscreen TVs; sometimes, you can hardly hear the dialogue in TV shows and movies. In one scene, spoken words sound so soft that you can't help but turn the volume up. Then suddenly, the next scene barges loudly into your living room, filled with explosions and gunshots, rattling your whole household with loudness only Michael Bay will appreciate.
As if a flatscreen TV's tiny speakers aren't bad enough, why is there so much variation in your TV's sound levels? And why is dialogue sometimes so hard to hear that you're forced to turn on captions each time?
Thankfully, we have a few tips for you that may just help you solve your TV's sonic deficiencies.
TWEAK YOUR TV SOUND SETTINGS
Before you take any drastic measures, try digging into your TV settings first.
Look for a section for audio and check for a setting called "Dynamic Range Compression" or "Dynamic Range Control." Try setting this to "High" or "Maximum." If your TV has this option, setting this to its highest level will flatten the range of volume, normalizing the loudest and the quietest sounds to a more consistent and equal level. This means the TV will lower the volume during intense action scenes (explosions, car chases) and boost it during dialogue-only portions.
Note: If you can't find this exact setting, it could be under a different label. Try looking for "Night Mode," "DRC" or "Normalization."
Apple TV
The current generation Apple TV also has this dynamic range compression feature built into it. It is called "Reduce loud sounds" and you can turn it on by going to your Apple TV's Settings menu, then look under "Audio and Video." While watching a video, you can turn this feature on or off by swiping down on your remote to access it via the Top Menu. Better yet, since Siri is available to serve you on the current-gen Apple TV, you can also conveniently ask the virtual assistant to "reduce loud sounds" to turn it on or "turn off reduce loud sounds" to disable it.
Sound Modes
Check if your TV has different sound modes for specific content such as Movie, Sports, News or Music. To boost dialogue volume, try selecting speech-enhancing modes like News, Clear Voice or a setting along those lines. While you're at it, turn off special "enhancements" like Dolby surround, virtual surround or 360 sound and see if that puts the dialogue further up front rather than the sound effects.
EQ
Another setting you can tweak is your TV's sound equalization or EQ levels. Most TVs, at the very least, have bass and treble controls you can adjust. If you find your TV dialogue to be a tad muffled, set the bass level to a lower setting for a less boomy sound and bump up the treble for more clarity.
