Emanation

[Brian Souvey]

I have a Bard who is singing “courageous anthem” in the next room. There is at least 1 wall if not more between him and the other characters, but they are still technically within 60-ft… the rules on pg 428 of the remaster phb don’t talk about cover, under emanation but there is a blurb about standard and greater cover effecting “areas”, am I safe to say, no they can hear you through the wall enough to be encouraged.

Not the remastered version, but walls will stop most effects:

Chapter 9: Playing the Game / General Rules / Effects / Line of Effect wrote:

Source Core Rulebook pg. 457 4.0

When creating an effect, you usually need an unblocked path to the target of a spell, the origin point of an effect’s area, or the place where you create something with a spell or other ability. This is called a line of effect. You have line of effect unless a creature is entirely behind a solid physical barrier. Visibility doesn’t matter for line of effect, nor do portcullises and other barriers that aren’t totally solid. If you’re unsure whether a barrier is solid enough, usually a 1-foot-square gap is enough to maintain a line of effect, though the GM makes the final call.

In an area effect, creatures or targets must have line of effect to the point of origin to be affected. If there’s no line of effect between the origin of the area and the target, the effect doesn’t apply to that target. For example, if there’s a solid wall between the origin of a fireball and a creature that’s within the burst radius, the wall blocks the effect—that creature is unaffected by the fireball and doesn’t need to attempt a save against it. Likewise, any ongoing effects created by an ability with an area cease to affect anyone who moves outside of the line of effect.

To find the remastered version of the rules that Taja cited, you'll want to turn back two pages to 426 and look under "Line of Effect." They are almost identical to the wording in the CRB.

Since solid walls are between the characters in question and the bard, those characters do not have a line of effect to the origin of the emanation and so will not be affected by the magic.
