The video shows an experiment where the host connects multiple headphones to a single phone using splitters. The host starts with 2 headphones, then adds more, eventually connecting 1000 headphones to the phone. As the number of headphones increases, the sound quality decreases and the volume becomes quieter. The host measures the decibel level, which starts at 38 decibels with 1 headphone and decreases to almost inaudible levels with 1000 headphones. Despite the low volume, the sound is still audible in all 1000 headphones. The experiment takes over 10 hours to complete, and the host is surprised that the sound continues to work with such a large number of headphones.
Here are the key facts from the text:
1. The experiment involved testing how many headphones can be connected to a single phone.
2. The first test involved connecting two headphones to a phone.
3. The sound quality did not change significantly when two headphones were connected.
4. The next test involved connecting four headphones to a phone using a splitter.
5. Four headphones worked, but the sound quality was slightly lower.
6. The experiment continued with connecting 8, 16, 32, 64, 128, and eventually 256 headphones to the phone.
7. With each increase in the number of headphones, the sound quality decreased and the volume became quieter.
8. The maximum sound level reached was 55 decibels with 128 headphones connected.
9. When all 128 headphones were disconnected, the sound level increased to 62 decibels.
10. The experiment concluded with connecting 1000 headphones to the phone.
11. It took around 10 hours to set up the 1000 headphones.
12. The sound was very quiet, but it worked in all 1000 headphones.
13. The sound level was measured at the beginning and end of the chain of headphones.
14. The sound quality decreased significantly with the increase in the number of headphones.
15. The experiment demonstrated that it is possible to connect a large number of headphones to a single phone, but the sound quality and volume will be affected.
