engine cover?

[AlsMaverick]

What is 1/2 db? I mean, 3 db is plus or minus 1/2 the sound. (Every 3 decibels up or down increases or decreases audible sound by two.)? How do you measure .5 DB, or is it subjective?

dB is a unit of relative power. For sound, 3dB the most common mentioned level because it is considered the lowest perceivable sound change to most human ears. No one is picking up 0.5 dB levels.
+/-3dB also happens to be the level at which power is change by a factor of 2, not sound.

There's also aftermarket options, like this one I had bookmarked, and now see is on sale at the moment:

Thanks for sharing. Added it to my Maverick mod list

noun

1. a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.
   
   So, it is a measurement of sound, in this case, as we are not talking about an electrical signal that carries information.

“The lowest hearing decibel level is 0 dB, which indicates nearly total silence and is the softest sound that the human ear can hear. Generally speaking, the louder the sound, the higher the decibel number.”

So, from zero dB, 3dB is twice the volume.

It basically says what I said. A dB is used to linearize, for mathematical purposes, the nonlinear nature of power. And I refute the very specific use of the words "electric signal" suggesting that information needs to be present. A dB is used for POWER of all types period.
I'm degreed Engineer. I understand it beyond the simplistic explanation found in you google search.

just a trivia point:

As a long-haul communications engineer, we were able to receive and in-encrypt intelligent communications from 22,500 miles away at -152dB, which is theoretically a point where no sound can exist.

And, I engineered communication systems for 40-years. You cannot measure an engine output in dB unless you are talking about sound, and by definition, a decibel is measured logarithmically, not linear as you proclaim.

A decibel is not “linear”. Even the name of the measurement will tell you it is a bell-shaped logarithmic curve.

Hello,
Can someone confirm if my new truck is supposed to have an engine cover?

Thanks
KT

NO.

Mavericks don’t have them.Extra $5-10 production cost that Mercedes and bmw kind of made common , been a waste as far as I’m concerned for the last 25 years or so in vehicle production , they really only are good for armoralling your NEW vehicle to make the engine compartment look less cluttered when your displaying your NEW vehicle at some kind of car show off.
Maybe good for about 1/2db in sound reduction of direct injection noises .
But sound deadoning on hood bottom would attain a lot better results ,cheaper ,if that is your goal .
I tend to drive my vehicle with hood closed , and my 87 bronco doesn’t have one or my 92 centurion . I noticed my sons xterra doesn’t have one or the 79 triumph tr7 I have with the corvette engine too .

I drive with my hood closed too! I hardly notice engine noise in the cab.

Word has it that Ford stopped installing engine covers on all Maverick models! It's apparently a money saving move, which to me makes zero sense!

When did Maverick models have them from the factory?

Shared info I attained from my dealer in Richmond when I took delivery of my 2024 Mav Lariat. Hope this answers your question.
