Class D amplifier headache

[riko4628]

Is it true that Class D amps can cause headaches? I mean that your head hurts after listening to it. I've noticed when we were watching something at school /w computer speakers (USB Powered - Class D) my head started to hurt.

No,that does not make any sense

 

[DUG]

I have not had that problem.

Poor speakers can literally cause ear fatigue. Maybe that can lead to a headache. You'd also have to consider what other "noise" might have been coming from the speaker.

Thanks a lot! Myth busted!

Yep to this!

Even without knowing what the computer speakers are like, it's still a safe bet they are the cause, not the amp.

Ear fatigue and headaches are chiefly the result of poor crossover design, mismatched driver dispersion characteristics, excessive resonances, excessive comb filtering and lobing as your head moves about, etc. IOW, a crappy speaker. Your brain basically gets exhausted trying to make "natural" a sound that is "not natural".

It may be the subject matter, not the system, causing the headache.

Thx for reply-s

I think the headache comes when you sit down for a design, optimizing the post filter feedback, choosing components, layout etc. That is headache!

Too right.

Decisions = Compromise

A lot of headaches are sinus related, changes in humidity, air quality, even posture.

Video issues are big for headaches too.

IMHO computer speakers+ poorly filtered SMPS power supply (which feeds the amp that drives the speakers, some maybe class T/class D, most others are class AB design) will cause ear fatigue.

also: because of inferior power supply (insufficient current headrooms, aka "current"), plus high distortion amps (with high THD figures, mostly spec'ed @ 10% with max. rated power output, etc.) and very inefficient small speakers (most computer so-called full-range speaker drivers are rated @ around 84dB @ 4ohms or even lesser efficient)....that's a recipe for disaster.

I had some cheepy CreativeLabs speakers that would cause ear fatigue after 10 mins of listening. Same amp on my JBL studio speakers can play all day long w/o any suffering.

Go figure.
