What is Your Signal to Room Noise?

When I play classical music, the neighbors invariably play with their two-stroke engines.

 

Sounds like you need some real cannons for your new performance of Tchaikovsky's 1812 Overture...

Just downloaded the first app that came up and this is what I got sitting at my computer where I listen with the AC blowing in a vent in the background.

This is at roughly the listening point (where my head is) after ~1 minute of Martha Argerich playing Chopin

During a louder bit of music.

Hi - Although it would inherently compare all of our figures, this is not how SPL is measured. This is at 1 meter distance from the speaker (some make that 2, but that is an other standard). So if I say I play at 85dBSPL, this was measured at this 1 meter distance. I know ... this makes it incomparable for room sizes and such.

Now what ...

 

Do you sit 1 meter from your speakers?

Do you ?

 

Roughly, yes...  ha. I listen at my computer.

As I suggested, it would inherently compare our figures (if it were about that in the first place). But it is just not how it is done. Nobody would expect it either. At least not me ...

 

You're free to ignore it if you like. it won't bother me any.

No ... It is just that I now think why we never talk in terms of "at the listening position". Thus, exchanging figures from that @1m rating actually don't compare (obviously). Still "we" always do it like that, and then somehow translate it to room size or forget thinking about it in the first place.

I think I mentioned that my 85dBSPL decreased to 81dBSPL at the listening position but there was an other reason to mention it.

 

There is a somewhat larger thread from [forgot the handle - cucumber something] about SPL from the orchestra hall and the listening room. Somehow we always keep talking about the 1m distance, or at least I do. It just is "in the system"; I think in the thread we're in currently, this started about real levels. So, you go to a piano, measure that at ~1m distance, go to the listening room and tune at at 1m from the speaker. Not the listening position. Again, obviously. But ...

 

I get what you're saying, I just don't think we were measuring our speaker levels at 1m in this thread, it started out in the OP about noise in the listening room. If I wanted to get the speaker measurements I would go to the SONUSFABER.COM and get them for you. ha.

 

I was just having fun with my new app and kept measuring things, because why not!

This is the album I used. It would really be something if we all used the same album as well.
