AI Thread Summary
Rated power refers to the maximum power a speaker can handle without distortion or damage. Impedance values like 4 or 16 ohms indicate the speaker's resistance, which is influenced by its inductors and capacitors. Frequency response measures the range of frequencies a speaker can reproduce, while sensitivity indicates how effectively it converts power into sound, with both metrics being crucial for performance. Channel separation in a speaker system, such as stereo or 5.1, involves distinct pathways for different audio signals to create a spatial sound experience. Efficiency is measured by how much sound output is produced per watt of input power, impacting overall design considerations.

Good day to all. I have some questions regarding speaker specifications:

1. What does RATED POWER of the speaker mean?

2. Why is the impedance of the speaker usually has a value of 4 ohms, 16 ohms etc, when speakers also contain inductors and capacitors in their drivers?

3. What is the definition of speaker FREQUENCY RESPONSE and SENSITIVITY and the differences between them?

I also would like to know:

4. How are the channels separated in a speaker system (eg. stereo or 5.1) ?

5. What are the essentials in designing a speaker(considering the power, voltage, volume-loudness, efficiency, etc.) and how to design?

6.How is efficiency measured?

Thanks a lot :smile:

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
