Minor Project - Televisions and Sound

With all this talk of high quality sound and high quality visuals, I decided to research a little into how the majority of people view and watch their content, at home on a television. Televisions are constantly changing the game with new revolutionary screen sizes and quality like 4K, but all this comes at a cost. All these changes to the display are actually affecting the quality of the sound. With making TV screens thinner and larger, the sound is becoming an after thought, when its just as important as the detail to visuals. You may not be fully aware if your television has bad audio.

"Ask yourself this: have you ever had to turn the volume way up to hear a line of dialog? Ever had miss entire sections of plot because there was so much going on on-screen that the jumbled mess was unintelligible? These are prime examples of bad audio.

The sound you hear is compressions and rarefactions in the air (the soundwaves), produced by a small moving object called a driver. To produce deep bass sounds, the driver either has to be very large, or have lots of power behind it. To produce very high sounds, the driver should ideally be fairly small. With enough processing and amplifier power, fairly small drivers can produce surprisingly decent sound. Modern TVs have none of these features."

This proves just how important sound is and my experiment will back this up. This also proves that television companies don't care about the sound their selling with their TV's as much as the visuals and their stunning "4K" quality. Now this could all be a marketing scheme to get you to buy separate speakers and spend more money, but when buying a TV you shouldn't just be buying the visual side, you should also be getting the same quality with your sound system in the TV. 

"There is no worse place to put a speaker driver than the back of a TV. Think about how someone sounds if they’re talking with their back to you. Not very clear, right? High frequency sounds are very directional. Sure, if your TV is near or mounted on the wall, some of the high frequency sounds will bounce back towards you (and in fact, this is how TVs with rear-firing speakers are designed to work). However, if the TV is out further in a room, you’re out of luck."

Maybe one day television companies will devote as much time and effort into their audio side as much as their visuals, as without quality sound, the TV could be considered worthless.
