Default please check me...

1. did I converted this harmonic distortion figures (from
dB to %) right?

fundamental is 29dB
2nd harmonic = 42.5dB (0.026%)
3rd harmonic = 62dB (0.0028%)
5th harmonic = 57dB (0.005%)
7th harmonic = 54dB (0.007%)

2.these are good results?

3.how are 5th and 7th harmonics affect the sound?

thanks!

Hello bogdan_borko,

1- If the fundamental is +29dB, and all your harmonics are -xxdB, then your procedure is OK

If your harmonics are xxdB below the fundamental then not OK. (e.g. the 2nd harmonic would be at 0.75%)

2- the 2nd harmonic is 0.027%
The others are OK For me these are good results. It does not mean that it is good sounding.

3- Hot question!

IMO, less is better for Hi-Fi.

Best regards

rephil

Hi bogdan_borko,

IMO : It is an abbreviation.
There are also some other shortcuts that are used as

'IMO' = In My Opinion
'BTW' = By The Way
'ASAP' = As Soon As Possible
'AFAIK' = As Far As I Know'.

You will see also 'LOL', very used, bur I have still to find what it means.

Do you know what it means ?

Regards

rephil
