Discussion Overview

The discussion revolves around understanding the relationship between acoustic impedance (z), density (p), and speed of sound (c) as expressed in the formula z = pc. Participants seek clarification on how to manipulate these variables to derive acoustic impedance.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant expresses confusion about how to use the formula z = pc to find acoustic impedance, indicating a lack of understanding of the variables involved.
  • Another participant asks for clarification on the definitions of z, p, and c.
  • A third participant provides definitions for the variables: acoustic impedance (z), density (p), and speed of sound (c), along with specific numerical values for the speed of sound and density.
  • It is noted that the participant is looking for guidance on how to apply the values of density and speed of sound to calculate acoustic impedance, mentioning a specific expected result.
  • A later post reiterates the formula z = pc, emphasizing that z is the product of p and c.

Areas of Agreement / Disagreement

Participants do not reach a consensus on how to proceed with the calculations, and the discussion remains unresolved regarding the specific steps needed to derive acoustic impedance from the given values.

Contextual Notes

There are limitations in the discussion, including a lack of clarity on how to manipulate the formula with the provided numerical values and the absence of detailed steps in the calculation process.

what do i do to p and c to get z when

z=pc

please help i know its prob dumb but i am so stuck.
 
Mathematics news on Phys.org
what is z, p, and c
 
acoustic impedance z
density p
speed of sound c

the speed of sound is 330 ms-1
density is 1.3 kg m-3
i need to know what to do with density and spped of sound to get acoustic impendance i know the answer is 0.00043 kg m -2 s-1 x10 but i do not know how to work out the formula?
 
z=pc means z=p times c.
 
thankyou
