Beagles hate to be alone. He may just be saying to you "Hey! Mom! Don't leave me here!! Hey!" My beagle did that for a loooooooong time. Unfortunately, time and finances don't always allow for some of us to just stay home with our fuzzy lil' companions. If you observe that it's a fear of abandonment that prompts the barking, perhaps leaving some music on or the TV for company may work - it kind of did for my little girl. She is now 13 years old and knows that when I turn on the raido and reach for her treats, she's really 'okay' with me leaving for work each day. By the way - the treats are yet another attempt you can try to dodge the barking bullet - distraction! Just scatter a hand full of cookies on the floor just before stepping out the door... it's like a little game of search and seisure for the pups and it keeps them distracted enough that you just might get out the door without alerting the entire neighborhood that you're going. Anyway, in the end, what REALLY seemed to help my Beagle out was 'routine'. Knowing that she was safe and in 'her' home and that we'd come back for her - like clock work - is what settled her down. Routine and acceptance and lots and lots of love. It was sooooooooo worth every second.

P.S. if it's not abandonment that Charlie's afraid of, but a person or an object (garbage truck, telephone, etc.) you can help him by helping him to confront his fears. Be with him, let him know that his 'pack' (you and your family) is with him and that he his safe. After much repetition and lots of patience and love, eventually, he should calm down and accept that what ever is upsetting him is not really going to hurt him and that he can rely on you to be there for him. Win/win.

Good luck to the both of you!
