Brain injuries from loud bass?

Repeated low-intensity impacts, like pulled sparring punches, can cause brain injury, but that's because of the brain hitting against the skull.

Explosions can also cause brain injury:

(Effects of Low-Level Blast Exposure on the Nervous System: Is There Really a Controversy?)
"...Questions have also emerged as to whether pathophysiologically blast-related TBI is different from the type of non-blast TBI (nbTBI) typical of civilian trauma where injury is caused by inertial and rotational forces along with the effects of blunt impact (37, 38). The most direct physical effects of these forces are bleeding, direct tissue damage, and mechanical shear stress along white matter tracts, which in turn leads to activation of a variety of pathophysiological cascades that are associated with further tissue damage (37, 39). Blast injuries by contrast result from a pressure wave generated at a distance and transmitted though air, which may induce stresses in the brain without significant global motions being imparted. Damage to the nervous system is thought to occur through biophysical mechanisms related to the traveling shock wave’s interaction with the brain (4042), although it has also been suggested that a blast wave striking the body can induce oscillating pressure waves, which can be transmitted through the systemic circulation to the brain (12, 43)..."

Loud bass frequencies can vibrate things visibly. If I'm listening to music in the car with loud bass, the rearview mirrors vibrate enough to be blurry, without a subwoofer, just on little factory economy car speakers. It's small impacts compared to boxing or explosives, but what about the cumulative effect with enough time? And with a louder bass amp?

Is it not commonly known that bassists are getting brain injuries just because of how weird the bassists already were? Is the SVT making me r-worded or is it not the SVT's fault?

I think my issues occurred long before I started to play bass. Playing bass probably didn’t help much..LOL!

I nearly got clocked one time. I turned around at one gig to see that my amp, a '90s Ashdown ABM800 which weighs a fair bit, was half hanging off the top of two 410's. It had vibrated right over. If that had dropped, it would have done some damage, either to the basses or me.
 
I have my hearing checked on a regular basis. I have normal hearing loss for a guy my age... 62. I listen to headphones cranked often and play at decent volume levels. To my knowledge I don’t have have any brain damage as a result of my bass playing..

I managed to escape major hearing loss as well. Three years ago I bought a pair of in ear filters “earsurs” (you can get these at Guitar Center for $30. Unlike foam ear plugs which make music sound dull and muddy are really don’t provide much protection, filters let’s most of the frequencies through, but at a cut of 15dB.

I did eventually invest in a pair or customs it in ear filters (Westone) from a local audiologist a year ago and opted for both 15dB for musical applications and a separate 25dB cut for lawn and garden work. These are also really great for a good night sleep in a noisy hotel.

One additional point of ear filters. For them to be effective, you need a good tight seal. I highly recommend you use Oto-Ease lubrication as you may have trouble getting them out of your ears.
 
One thing to consider, at least for Metal musicians. Headbanging, fast and hard, causes the brain to slosh around in the skull. Over time, according to my doctor, that can lead to mild brain injury. It's like getting multiple concussions, although very mild ones, but the effects are cumulative. It can also do damage to the vertibral discs and cartilage in the neck.

^YUP. Tom Araya from Slayer had to get a rod installed in his neck from all the headbanging. He then had a special harness made for his bass that put the weight on his waist rather than his neck/back. I used to headbang like crazy on stage when I was younger.

I did too. That's why I discovered the joy that is cumulative whiplash injury to my neck. I haven't needed a rod, but there is definitely damage. Discussing the neck injuries is what prompted the doctor to tell me about the concussive effect. Doesn't help I played football and hockey for 15 years.

Wow it's like I am looking in the mirror! But it's my back that is the culprit. These things add up and advancing age does NOT help :D
