I don't think the mesurement is misleading. That is what the mesurement is. Each person has different tolelance level. Definately, it is not as loud as SP10 for sure, but it is a different type of noise. It is not a high pitch like SP10 but it is a noise from the high speed fan and the PSU cooling.
The noise is difinitely more than S3 x 1. May be a bit more than S3 x 3-4 units. Its not a fair to compare against 1 S3 vs 1 S4. Power consumption between these machines are more than 4x higher.
Members here wanted to know the reading and specifically asked for it, so I powered up my S4 and provided 2 different mesurements. (I did the same with S3 when it first came out.) Not what I think cusotmer shoudl know, but I try to provide what customers want to know.
That decimal reading is from 1 unit, we may try with stack of a few units in a quiet place & will have an amp reading as well.
Side Note, I love my SP10 but I can't take the noise it make. DBA reading wise, it is more than S4 and it is high pitch. S4, yes, I don't want to be working next to it for 8 hours a day while it is hashing but it can be tolerated a bit more than SP10 noise. (This is not a bedroom space heater option but it can be the space heater in the garage, or basement or in the spare bedroom where a bit of larger fan noise is not an issue)
That dba rating is why I stopped measuring in my reviews - they're misleading. 74 is very, very loud but at the same time you're saying its not much louder than an S3? And the video suggests not much louder than an S3 or an S2. I think its a lot more about sound quality than sound pressure. Some of my units are incredibly annoying but are 10 dba quieter apparently than others.

More info for S4...
To Power up S4, you have to hold a little nob (switch) on the PSU for 2-3 seconds. Then it will power up. Other wise, you may think it is a DOA like S2 used to be
Video from Bitmain as more infomation regarding the S4. I think this is easier than someone try to word how noisy it is
It push & Pull massive amount of air!!!

S4 does come with 2 server ears. (There is NO POWER CORD included) The box is well packed!!
