When the plot is normalised dB SPL is not offered as an option.
2, click Blank workbook (PC) or Excel Workbook (Mac).
The mic (umik-1) was just 15 cm from the speaker, hence the relatively high SPL measured - the levels correspond to about 85 dB at the listening position, about 70 cm from the speakers.Distortion Examples - speaker measurements Speaker measurements, particularly those made in-room rather than with the benefit of an anechoic chamber, present additional challenges for interpretation.Similarly the third harmonic plot can only be generated.67 kHz (20/3).Question How do I title the graph?Temme in "How to graph distortion measurements" presented at the 94th gezicht smaller maken make up AES convention in March 1993.
As an example, suppose the loudspeaker response was flat apart from a 6 dB peak at 2 kHz.This will select all of your data.That dip is probably due to the crossover between mid/bass and tweeter integrating poorly at such a near field measurement position.Normalising the plot will cause the distortion traces to rise at high frequencies if the response of the system being aardappelsoep maken measured rolls off (as is usually the case).If you want to copy from excel and paste to word, for instance, then right click on the graph and select 'copy' from the drop-down menu, and paste it into your word document.Click on the element you want to adjust.Convert lengths, areas, weights and temperatures.Although much, much slower than a log sweep the stepped sine measurement can measure low distortion levels much more accurately than a sweep, particularly at high frequencies and for higher harmonics.

This is the impulse response for the in-room measurement, the distortion peaks are clearly visible to the left of the main peak.
