Middle English hummen, of imitative origin.(American Heritage® Dictionary of the English Language, Fourth Edition)
From Old English hommen "make a murmuring sound to cover embarrassment," later (medieval English) hummen "to buzz, drone" (c.1420); akin to (medieval and modern) Dutch hommel 'humblebee', medieval German hummen 'to hum', probably ultimately of imitative origin (Wiktionary)
