Moderate hearing loss (41-55 dB): it may affect language development and articulation, interaction with peers, and self-esteem. Patients with this degree of loss have trouble hearing conversational speech.

Moderate-severe hearing loss (56-70 dB): it may cause difficulty with speech and decreased speech intelligibility. Patients with this degree of loss do not hear most conversational-level speech.

Severe hearing loss (71-90 dB): Severe hearing loss may affect voice quality.

Profound hearing loss (>90 dB): With profound hearing loss (deafness), speech and language deteriorate.
