Starfleet computer consoles are rather noisy. I can understand — especially with 24th Century touchscreen LCARS consoles — why they might be designed to emit sounds when pressed. (This way, you'll know if you have inadvertently initiated a photon torpedo launch when you were resting your hand on the tactical console...)
But the consoles also make plenty of noise while they are retrieving information, for instance at 00:16s in this compilation:
Present-day computers make unavoidable hard-drive whirring sounds while accessing data, but do not purposely make sound effects to indicate that data is being accessed (at least not typically).
Why are Starfleet computer consoles so noisy?
I perfectly understand the out-of-universe reasons for this — it makes sense from a production point of view, as it helps to create the atmosphere. I'm asking for in-universe reasons. Why would Starfleet engineers add so many sound effects to consoles?
Speculation is fine, but something official — such as a statement from Michael Okuda or a technical manual entry — is preferable.
