Spring is here and summer is coming! So after spending (part of) my winter holidays analyzing the vibrations on a snowboard (and proving why it’s better than skiing, check here!<\/a>), I\u2019ve decided to take out my e-bike for a ride. Another good reason to do so, is the fact that today – June 3 – is World Bicycle Day<\/a>.  <\/p>\n\n\n\n

E-bike sounds<\/h2>\n\n\n\n

E-bikes are becoming more and more popular these days, and a lot of different brands exist. An important criterium for end users is their operating range. But also the e-bike noise is an important aspect for both manufacturers and end users. <\/p>\n\n\n\n

When talking about \u201cnoise\u201d, I do not only mean the decibel (dB) value of the overall noise level. This dB value is something you typically measure with a sound level meter or via an ISO sound power test. I wanted to get a better understanding of the acoustic quality comfort that e-bike riders experience.  <\/p>\n\n\n\n

So I took my backpack and the Simcenter SCADAS XS<\/a> with its binaural headset to record some sounds. As the measurements took place outside, I added the windcaps to protect the built-in microphones from disturbing wind turbulent noise.<\/p>\n\n\n

Since the SCADAS XS has an additional 12 channels available, I decided to take it a step further and instrument the e-bike with more sensors. After all, why not? <\/p>\n\n\n\n

Next to the binaural headset, i added the following sensors: <\/p>\n\n\n\n
