It's best not to play prenatal music on the computer, especially with mobile phone MP3 and multifunctional small household appliances (such as small speakers with cards and inferior CD toasters). Most of these things are low-cost functional circuits, with serious audio amplification distortion and poor music quality. Using this kind of music with poor sound quality for prenatal education is very harmful to the baby's hearing. And you can't listen with headphones. Adults can only entertain themselves by listening to headphones, but the fetus can't hear them. The harm of baby listening to headphones is to damage baby's hearing. The best effect is to buy a stereo with a power amplifier, and the better one costs 10 thousand yuan, which is not necessary. If conditions permit, you can buy a stereo of several thousand yuan, a small CD all-in-one machine with better quality, and the CD-ROM drive of the computer is the worst. The first choice of prenatal education music is Love and Music, Raymond Rapp's Fantasy World of Baby and Mozart Effect. If the economic conditions are good, it is a better choice to listen to some classical music handed down from generation to generation. Be sure to choose high-quality CDs made by well-known professional audio and video companies. These CDs are very expensive. The best way to save money is to choose mirror discs made by enthusiasts. The sound quality made by experts is exactly the same as that of genuine products. The quality of online downloads is very poor. Remember, MP3 and other online music must not be used for prenatal education! ! ! It's okay for adults to entertain themselves. There is a mirror image of music fever master on Taobao, which is shared at a low price. The price is very cheap. The electronic version of lossless mirror image file only costs more than 20 yuan, and the engraving effect is quite good. Suggest the landlord to have a look. The name of the Taobao member in that small shop is: Global Wangpu (Recently, many netizens said that they were cheated by impostors. If you don't want to be fooled, don't search the internet. Use your Taobao Want Want to directly add "Global Shop" to ensure that you will not be cheated by impostors. It should be noted that when buying Ai He Music, you should pay attention to the quality of the file, and never use MP3 format. MP3 is very distorted and cannot be used for prenatal education. I bought the original file without any distortion. If there is no special requirement, the general merchants will send you files in MP3 format. Because MP3 files are very small, only one tenth of the size of the original image files. Very easy to send. However, the original image file also takes time to download and burn, but if you pay more, the seller will burn the CD for you. They are more professional. In order to save money, I burned my own CD, although even music lovers said yes. But burning files in this format is really a lot of unexpected trouble, wasting a lot of discs and time. Calculate an account, it is better to buy a burnt one!
