Psychological biases are huge but for the purposes of this good-faith discussion I'm assuming they're controlled for.Ī suite of measurements such as those produced by e.g. Thus any claims of audio qualities, for lack of aīetter word, are by definition psychological biases I don't believe we need to know all there is about hearing to answer that question. However, it seems to me that the question is, "can System A reproduce sound with a 'sound quality' relative to System B that cannot currently be measured, but can be recognized by listeners?" Hearing involves the human brain and I'm absolutely sure we don't know everything there is to know about it. Is that we know all there is to know about hearing However it seems an implicit assumption in your statements Anybody telling you otherwise is simply uninformed, or trying to pull the wool over your eyes and sell you something. And those 1's and 0's in a digital audio stream for example have objective meaning. Those pressure waves can be objectively measured in terms of frequency and amplitude. As you know, "sound" is pressure waves in the air. And even Floyd and Toole's research reveals average listener preferences. Everybody's hearing is a little different. There is also room for subjective personal preference. We can objectively measure what is good and isn't good. Ultimately though, audio reproduction is not wine tasting. A lot of brands try to achieve a bit of a house sound. Of course, audio companies do tinker with their sound to some extent for subjective purposes. and/or measurement devices like Audio Precision gear: and/or measurement devices like the Klippel NFS to simulate anechoic measurements. This would be a remarkably laughable and irreproducible way to calibrate audio reproduction devices.Īudio technology companies that are serious about high quality sound reproduction make use of anechoic chambers. A person's hearing can change rather markedly from day to day due to factors like congestion, humidity, etc. I don't realize it because it's not true. In the end, it's signal reproduction.ĭo you realize that all gear is tuned by ear - someone The TL DR is that it turns out that most people prefer sound reproduction that (like video reproduction) is accurate to the source material, with a bit of a "house curve" that accentuates the bass frequencies that roughly corresponds to the Fletcher-Munson equal loudness curve. Here's probably your best starting point. You'd want to look into research by Sean Olive, Floyd Toole. As rational minds might expect we don't live in such a world. A world where we can calibrate televisions and movie screens objectively by automated means but not, for some reason, their audio counterparts. Hope you've got time to read.įirst, I want you to consider for a moment how remarkable it would be if we had no idea how to objectively measure "good" sound considering that this is a multibillion dollar industry that has existed for over a century. Please cite actual research defining "objective audiophiles" Should you experience noises, cracks, hum and static when connecting the netbook to an amplifier and to a mains adapter, that is a common problem of ground loops and not of that particular netbook, that will be easily solved by adding a small audio transformer in between. If you want a music player that you can control from another room, you can do that by installing a very small distro such as the x86 Alpine Linux image ( ) then the mpd daemon ( - it's in standard repositories install it with "apk add mpd" from root shell) which can work headless, therefore requiring very few resources, then a suitable control app for your phone or tablet (search for mpd control app), so that you can do pretty much everything through your home WiFi from any room, basement, backyard, etc. The EeePC 701 netbook is a really minimal underpowered machine, still it will run small Linux distros just fine (it was actually sold with Linux in the first place). "It turns out that nothing really runs well on a 32-bit x86 machine anymore, including major Linux distributions and web browsers."
