How Does Removing Pigs Affect the Decibel Level in a Pig Pen?

AI Thread Summary
The noise level in a pig pen with 213 pigs is measured at 78.1 dB. When 77 pigs are removed, the remaining pigs are assumed to maintain their original squeal intensity, prompting a calculation of the new decibel level. Additionally, the discussion compares the intensity of an orchestra at 87 dB to a single violin at 62 dB, highlighting the significant difference in sound intensity. The forum explores how to derive the intensity of sound produced by one pig using the decibel definition. Ultimately, understanding these sound levels can provide insights into the impact of pig removal on overall noise in the pen.

1- The noise level coming from a pig pen with 213 pigs is 78.1 dB. Assuming each of the remaining pigs squeal at their original level after 77 of their companions have been removed, what is the decibel level of the remaining pigs? Units dB

2- The intensity level of an orchestra is 87 dB. A single violin achieves a level of 62 dB. How does the intensity of the sound of the full orchestra compare with that of the violin’s sound? Find the ratio

You know the noise level and the total intensity. How can you, using the information you have, solve what intensity one of the 213 pigs has?

Hint: Use the definition of decibel.
 
Ardahl O`Hanlan wrote a book and remembered listening to Radio Luxembourg for the Pop music . He said the reception was so bad it sounded like they were --- Deep frying a herd of live pigs.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
