Everyday Speaker Sounds of Audio and Video

Live sports, to Pandora, to FM to on-demand DVR'd reality shows. Broadcast or recorded sound is a century old. 

On-demand sound evolution:

• Turntable records
• Car radio 
• Box-rocker portable stereos 
• Modern-day: stand-alone media room in our pocket or on our wrist 

One-way and two-way audio systems are a non-stop feature in the 21st century. Waking up, working, and falling asleep to a preferred sound, such as music, is a constant for many people.
