Does storing IEM in positive pressure (tupperware) damage driver?

post #1 of 8
Thread Starter 

I am just wondering if storing IEMs in Tupperware or waterproof box with positive pressure damage or deform the driver diaphragm in the long run? I always imagine some IEMs make driver flex sound as they are placed in air-tight containers...

Westone 4R come shipped in a mini Pelican style box, so I kinda don't it. Just my thoughts.

I'm guessing that there will not be any problem for the BA drivers. Dynamic drivers might have this problem. But it really depends on how much additional pressure dues the box puts on the drivers itself. Then again, why do you need to store them in Tupperware? A normal box will be fine, even an Altoids tin will be sufficient for the job.

I wouldn't think a Tupperware container would be that much of a pressure difference. 

 

Also, why not a plastic bag?

Yeah, I do wonder if BA and dynamic are affected by pressure differently. Maybe it's part of the reason westone adventure series doesn't come with the pelican case.

I considered using altoid case, but didn't want to run the risk of it rusting. And I happen to have some small Tupperware sitting around that's just the right size. Didn't want plastic bag or cloth pouch because things can still get squashed.

Not sure why you want to store your IEM in a tupperware, I use Ikea plastic storage boxes which are perfect...

 

I think the name is SAMLA

Kind of OT, but I think you're talking about negative pressure, rather than positive pressure.

 

Positive pressure refers to the state where the container is of greater pressure than the atmospheric pressure, and thus gas exchange will flow outward from the container to the atmosphere, e.g. an operating room or a commercial airplane cabin.

 

Negative pressure refers to the opposite, where gas exchange flows from the outside in, such as a quarantine room in a hospital (to prevent pathogens from leaving a room).

 

When you evacuate air in a vacuum, the resulting pressure gradient is of a negative pressure state.

 

Regardless, the kind of situations you're referring to will not be of any consequence to any driver diaphragm, regardless of type, as the pressure gradients are just not that great.

I'm pretty sure it's positive pressure before "burping" a Tupperware container. But yeah, I guess it's not that much pressure difference.
