Lossless WAV speed listening, hearing science and gear.
🔬 Sound science
A Korean science documentary measured what 10 minutes of MP3 does to the body. Reaction time, muscle response, plant growth — and a fetus that winced in one second.
🔬 Sound science
Degraded audio costs you even when comprehension is perfect. Pupil dilation, dual-task accuracy and reaction time put numbers on it.
🔬 Sound science
Speech compressed to 2–5× hands the brain a harder-than-normal task. Start with Korean you already understand, and the processing speed you build transfers to English.
🔬 Sound science
At normal speed the speaker’s voice barely matters. At 3–5× it decides whether you still hear the consonants. Vowel space, time-stretch artefacts and brain load explain why.
🔬 Sound science
The Lancet: around 40% of dementia is preventable, and hearing loss is the single largest modifiable risk factor. Here is the evidence, cited.
🔬 Sound science
Studio masters are uncompressed WAV without exception. What reaches your ears is FLAC, ALAC — or usually MP3. Here is what happens in between.
🎛 Gear
A file of ones and zeros is not sound. A DAC turns it into the analog vibration your ears feel — and that little stick you plug into your phone is exactly that.
🎛 Gear
Listen over Bluetooth and most of what makes BrainHz different — lossless WAV and restored high frequencies — is gone. Here is why wired is the rule.
🎛 Gear
Feed in 48 kHz lossless and it still fails if the receiver smears the signal — the brain goes back to reconstruction work. Why the receiver matters, plus three picks by situation.
🔬 Sound science
Vinyl is analog, CD is digital. Here is the whole landscape sorted into three simple buckets: analog, digital-lossless and digital-lossy.
🎛 Gear
Over Bluetooth the Charge 6 is lossy, but connected by USB-C it plays up to 24-bit/96 kHz lossless. Here is how to switch it on.
