Sadly, not being able to focus on wanted sounds and ignore unwanted sounds is a sign of ageing hearing.
I was demonstrating a Nintendo brain-training game to my parents once and they asked if I could turn the music down – it was already very low level, but they could not filter it out.
Television companies do spend a lot of time and money achieving very high sound quality – easily as much as vision quality. However, they use very expensive amplifiers and speakers in the sound control rooms, which do sound amazing and it is very easy to pick out what one wants to hear when listening to those.
In the home however, television speakers and amplifiers are usually very small and very limited and they cannot reproduce the full dynamics and frequencies, so they "muddle and scramble" the sound to some degree.
What can be tried is that many televisions have a variety of sound or audio settings in the menu, some including a 'clear-voice' setting for speech. Worth trying them all to see what they sound like.
Some have user definable audio equalisers – like a tone control but with 6 or more channels instead of just bass and treble. Try reducing the level of frequencies in the 250Hz – 500Hz range and boosting frequencies in the 3,000Hz (3kHz) – 5,000Hz (5kHz) range. This will increase speech intelligibility, while reducing the apparent volume of the overall sound. I did this for my parents who reported a clearer sound, and they did not need it as loud overall as before.
Having a sound bar or a good set of speakers is another way to go. Adams Audio, a German company, make semi-pro studio monitor speakers with built-in amplifiers, such as their T7Vs. I have a pair of these fed from the headphone output of our TV. These speakers are absolutely incredible and a pair are cheaper than many sound bars. We can now hear a whole lower register of sounds and music, such as car doors slamming, double basses in the orchestra etc, and the speakers and amplifiers are so good and neutral that voice reproduction is clear.
Adverts do annoy me though. They compress the volume, so they sound much louder, even though, technically they do not peak much louder than the normal audio. My finger hovers near the mute button for all adverts and trailers.
I have no connection to Adams Audio.
