Pronunciation: [dˈʌlnəs] (IPA) 
The word "dulness" is spelled with double "l" and not a single "l." The reason for this spelling is due to the vowel sound in the word. The IPA phonetic transcription of "dulness" is /ˈdʌlnəs/. The "u" sound is pronounced as /ʌ/ which is considered a short vowel but is distinct from the sound of a short "o" /ɒ/ as in the word "doll." The double "l" in "dulness" represents a syllable break between the "u" and "n" sounds.
