Re: Impulse responses

Sorry, I missed your post.

It isn't essential but it does help by making all graphs the same scale so that people can compare them to theirs and offer advice/opinions.

Re: Impulse responses

is it importante the calibrated spl level to understand the response of the room ? I mean, room modes and reverberation time.

Do you own, or can you borrow, a smartphone?

There are free Decibel meter/SPL Apps available that are good enough to set your levels for testing.

Hi Lesmor,
I didn't set a reference level for spl, just check that the level was ok for rew
mic: Dayton 8098 with calibration file
the lower cutoff frequency of Genelec 4080 from technical spec is 45 Hz
From what I can gather your readings are too low.
What is the noise floor of your room?
In the meantime perhaps have a look at this video

Re: Impulse responses

@angeloconto
Had a quick look at the data
I am in no way a expert

What SPL did you set for the measurement as it looks to be too low?
What microphone are you using?
The Graph seems to roll off at 70 Hz is that the -3db cut off of the source if so there is no usable bass data.
Looking at the impulse response there seems to be a lot of reflections.
Sorry for all the questions but just trying to get a feel of what you are actually looking for.
