Nel: There are two positions that are relevant?
Nel: You were there and if you turn to 937 it is a different angle.
Nel: 938 is a direct line of sight to that door?
Lin: Yes, I have seen that one.
Nel: Now the window you allowed for 25db, we cannot say that is a bit much?
Lin: It is typically an assumption but a allowable assumption.
Nel: If I indicate to you that 25db is used for a solid window that is sealed.
Lin: Typical domestic window, closed can go up to 30db. I have measured this on a different site.
Lin: If sealed it can measure more depending on the glazing.
Nel: And you took all this into consideration?
Nel: The same with the door?
Lin: Not 29, that is for the entire path of the sound if it is generated through the door.
Nel: Now, again. Before I step up, we have a variable, we do not know if the window was sealed properl.
Nel: Page 12, for the person standing at the listener side, I understand all the variables. I am just testing your model. A listener would hear a sound of 40db?
Judge: You are still dealing with 177 meters?
Nel: Referring to page 73, your graph.
Nel: If I interpret your graph, your table. Everything you took into account, the level would have been 40db?
Lin: The highest range, yes.
Nel: The last entry is 22dba, that is if the window is open at the listener's side?
Nel: That is at an average of 110dba from source?
Nel: Then, you deal with, if I read your table correctly. What do you mean by intelligible?
Lin: Possible to perceive information.
Judge: I am still not sure.
Lin: There is a definition that I put under 4.8, on page 3. May I read it for you?
Lin: It is a process that involves human involvement.
Nel: What ever we deal with, it depends on the power of hearing of the listener?
Nel: But in this instance we do not have it?
Lin: We do not have it, yes.
Nel: Why I am asking is although, you deal with it in a heading. The reliability, you don't make a finding on someone's ability to hear a scream at the distance?
Nel: SO I have to take you back. You were quite correct earlier.
Nel: What we have in this instance is four people identifying the voice as a woman's voice?
Lin: I actually don't know what the exception was.
Nel: In this instance there is no exception, every-body that heard it, said it was a woman's voice.
