Defining and calculating speaker’s sound pressure
levels (SPL)
The recommended SPL (Sound Pressure Level) for different applications depends on the purpose
of the audio (e.g., speech, background music, or announcements) and the ambient noise level of
the environment.
Here’s a practical reference chart for commonly encountered commercial spaces:
Application
Recommended
SPL
Purpose Notes
Meeting Rooms 65–70 dB SPL
Speech clarity
Keep just above ambient
noise; avoid listener fatigue
Classrooms
65–75 dB SPL Speech + AV audio
Aim for clear intelligibility at the
back of the room
Cafeterias
75–80 dB SPL
Announcements, ambient
music
Slightly louder to overcome
crowd noise
Restaurants
70–75 dB SPL Background music, paging
Should not interfere with
conversation
Retail Stores
70–78 dB SPL Background music, ads
Volume can vary by vibe/brand
identity
Offices (Open Space)
60–68 dB SPL Paging, low-level BGM
Soft enough to not distract, but
audible
Lobbies & Corridors
68–72 dB SPL
Announcements,
background music
Balanced to avoid echo and
blending with ambient noise
Factories / Warehouses
85–90 dB SPL Announcements, alarms
Must exceed ambient noise for
clarity and safety
Outdoor Areas
75–85 dB SPL Paging, music
Depends heavily on
environmental noise and
coverage area
Auditoriums
80–95 dB SPL Speech, music, live events
High dynamic range required;
use zoning and delay speakers
