The Smart Access Memory feature is far from perfect. And although it is a useful technology overall, it also proves to be very unstable. What was true today may not tomorrow, and an in-depth analysis shows all those patches. On the one hand, those that eliminate the biggest problems that no one boasts about, and on the other hand, those that raise average performance in small steps.
Frequency response of sound
Measurements are performed in the TrueRTA application, which records sound in a range of 240 frequencies in the recorded range of 20–20,000 Hz. For the possibility of comparison across articles, we export the dominant frequency from the low (20–200 Hz), medium (201–2,000 Hz) and high (2,001–20,000 Hz) range to standard bar graphs. However, for an even more detailed analysis of the sound expression, it is important to perceive the overall shape of the graph and the intensity of all frequencies/tones. If you don’t understand something in the graphs and tables below, you will find the answers to all the questions in this article. That explains how to read the measured data below correctly.
