Homework Statement



You are trying to decide between two new stereo amplifiers. One is rated at 130 W per channel and the other is rated at 200 W per channel.
In terms of dB, how much louder will the more powerful amplifier be when both are producing sound at their maximum levels?


Homework Equations



dB = 10 log (I/Io)



The Attempt at a Solution



I was not sure If i can use the 130 W and 200 W as intensities...

Power is proportional to the intensity so yes.
 
  • #3


so the solution is :

dB = 10 log (130/200) ?
 

1. How do I know which amplifier is better for my needs?

To determine which amplifier is better for your needs, consider factors such as power output, features, and compatibility with your current audio setup. Research the specifications of each amplifier and read reviews from other users to help make your decision.

2. Is there a significant difference in sound quality between the two amplifiers?

It is possible for there to be a difference in sound quality between two amplifiers, however, this can vary depending on personal preferences and the specific specifications of each amplifier. It is recommended to listen to both amplifiers with your own music to determine which one produces a sound that you prefer.

3. How reliable are these amplifiers?

The reliability of an amplifier can vary greatly depending on the brand and model. It is important to research the reputation of the brand and read reviews from other users to get an idea of the reliability of each amplifier. It is also recommended to purchase from a reputable retailer that offers warranties and returns in case of any issues.

4. Are there any notable differences in price between the two amplifiers?

The price of an amplifier can vary greatly depending on the brand, model, and features. It is possible for there to be a significant difference in price between two amplifiers. Consider your budget and the features that are important to you when comparing prices.

5. Will either of these amplifiers be compatible with my current audio setup?

It is important to check the compatibility of each amplifier with your current audio setup before making a decision. Look at the inputs and outputs of each amplifier and compare them to your existing equipment. Also, consider the power and impedance requirements of your speakers to ensure they will work with the chosen amplifier.
