My son likes to turn up the Volume when watching TV (YouTube and Disney+). As a result the music in the show is particularly loud.
Maybe he have a mild hearing problem, maybe he does not understand what the character is saying as he is still young, maybe the background noise in the house is loud (mum cooking). Or maybe the TV speaker is crap.
I am leaning to TV speaker being crap because my experiences with mobile phone VS computer headphones in a conference. I struggle to hear things when I am connected to conference with mobile.
So my question, will a soundbar help make dialogues clearer? Like a Bose Soundbar 700 or equivalent?
It depends how bad the speakers are. Some TV speakers are complete junk, especially since the trend towards being thin for the sake of being thin. Cost is also a factor.
That said, music and sound effects are louder than dialogue in movies.
