Cologne / Hameln (dpa / tmn) - If you are in the car, you should not do without one thing: the personal playlist. Because if you trust that there is always a radio station that suits the route and mood, you will almost certainly be disappointed.

A classic way to bring your favorite music into the car is to digitize a CD collection on the computer. “If you own a lot of CDs, you can't avoid changing your music library in the long term,” says car hi-fi specialist Michael Zeitler, who runs a specialist dealer in Cologne. "New devices still have CD and DVD drives, often also connections for SD cards and USB sticks, but not CD changers."

Take the stick with you

The easiest way to get the music files into the car is on a USB stick. Large sticks with 64 gigabytes (GB) cost less than ten euros and can store thousands of songs. On this occasion, the music files can also be stored in an online storage. Because even in cars, music comes more and more over the Internet. "In the long term, all of the music is stored in the cloud or loaded by streaming services," says Zeitler.

There are differences in sound quality between the individual music file formats. These can be set according to the program during digitizing, the so-called ripping. "Music fans who value the maximum quality of their music collection should save the songs in FLAC format," advises Zeitler. FlAC stands for Free Lossless Audio Codec, a powerful format that compresses the music losslessly, unlike MP3 or AAC.

Nothing works without a bracket

If you subscribe to a music service anyway, you can of course also use it to stream in the car - provided a stable holder and power supply for the smartphone is required. Whether the connection to the car radio is established via a USB cable or Bluetooth is irrelevant, says Zeitler. If you have to skimp on your monthly data volume, you should use the offline function of the music service app and download your music at home via WiFi.

Matthias Wagner, member of the board of the Car Akustik retail group, often uses another type of music via smartphone. He accesses songs in the car that he has saved himself on the phone: "I always have my cell phone with me, it stores all my favorite songs." They also come from a digitized CD collection.

The said holder for the smartphone in the car is particularly important. Because the StVO regulates that the cell phone may not be picked up or held while driving. When operating and using the smartphone, only “a brief glance that is adapted to the road, traffic, visibility and weather conditions” is permitted.

It shouldn't be the rolling disco

And even if listening to music while driving is fun: you shouldn't overdo it. A rolling disco not only damages your hearing, but can also be dangerous and annoying for other road users. But what is too loud? The extent to which motorists can turn up music is not precisely regulated. According to the Road Traffic Act (StVO), the driver is responsible for «ensuring that his vision and hearing are not impaired by the crew, animals, cargo, equipment or the condition of the vehicle.»

“Drivers always have to make sure that they can still hear traffic while driving and listening to music. This includes horns from other vehicles, sirens from emergency vehicles and the ringing of bicycles, »says Kay Schulte, Head of Accident Prevention in the German Road Safety Council (DVR).

Headphones in the car are taboo

"There is no exact decibel number," explains Schulte. If the driver and front passenger can still talk without shouting, the volume is usually still acceptable: "It is important that the driver can still hear outside noise outside the car."

Schulte expressly warns against wearing headphones in the car because the driver is more or less completely isolated from outside noise - especially with in-ear headphones, acoustically closed headphones and, of course, with noise-canceling headphones with active suppression of outside noise and - noise.

Info box: That makes music with the driver psych

Can music in the car be stressful or even dangerous? Ralf Buchstaller, technical director of the Medical-Psychological Institute of TÜV Nord, does not consider listening to music in the car to be particularly disturbing. "But it always depends on the traffic situation, the psychological situation of the driver and whether the music itself is determined," says Buchstaller.

Also relax the music when the overall situation is relaxed. In stressful situations, for example when looking for a way in a foreign city, the music can definitely disturb, says Buchstaller. «But there is no difference in the style of music. Most drivers choose music that calms them anyway. »
