The average level of conversational speech is 65 dB SPL +- dB.

The average level of conversational speech is indeed approximately 65 dB SPL. This level is considered standard for normal conversation within a typical environment, where people are usually speaking at a comfortable volume to be heard by someone just a few feet away. Understanding this baseline is crucial for hearing aid specialists, as it helps in fitting hearing devices to ensure they adequately amplify speech sounds to levels that patients can comfortably hear.

While variations can occur based on environmental factors and the individual speaker's vocal intensity, the general reference for conversational speech is categorized around this 65 dB SPL mark. Recognizing and applying this standard allows hearing specialists to properly evaluate hearing loss and recommend necessary interventions. Factors like age may influence overall hearing ability, but the general average level remains a consistent benchmark for therapeutic purposes.
