All functions need parentheses. When changing the order of operations you need them. See the related question below.
Functions are basically built-in formulas in Excel. They are used extensively in Excel, so it is very important to know how to use them.
Most formulas in Excel are quite basic, such as formulas for SUM functions. You use them in all sorts of situations, so it is very much a case that you use them when you need them. In that way, there is no specific answer to the question. So you use a basic formula when you need to use one. You would not use a very complicated formula, when a basic one will do.
There is no specific formula or function for sound in Excel. As there are mathematical formulas for sound, like ones for speed of sound in water or in air, you can use Excel to do the calculations if you know what those formulas are.There is no specific formula or function for sound in Excel.

You can use the LEN function to count characters in a cell. You can also use it to count characters in multiple cells. You need to know how to do array formulas to do that.
There might be a situation in which you would use a comma before a parenthesis, but generally you do not do this. A pair of parentheses already sets its contents apart from the rest of a sentence, so there is no need for a comma to precede the left parenthesis.
Cells are the fundamental element of a worksheet. All formulas are put into them. Most functions and formulas will reference cells on the worksheet. So cells are extremely important in Excel. Without them, you do not have a worksheet.
Every worksheet you create is different, so will have different formulas. You will commonly have ones for things like adding, multiplying, dividing and subtracting, but their exact construction can be different in each worksheet. What you really need to know are the fundamentals of how to create formulas and how to use common functions in formulas, like SUM or AVERAGE. There are other things that will help you in building formulas like how to use relative, mixed and absolute references.
