Acoustic Panels – When Thickness Counts
Today’s architects, builders, and designers are more aware than ever of how acoustics shape the experience of an interior. Whether it’s a boardroom, auditorium, gallery, or gymnasium, sound control is now seen as essential—not optional. Clients expect clarity of speech, reduced echo, and a comfortable noise level.
One often-overlooked factor in acoustic design is the thickness of the panel used. While all acoustic panels help reduce reverberation, thicker panels absorb a broader range of frequencies—especially low-frequency sounds that are harder to control. These low-end sounds are common in music venues, public address systems, sports halls, and performance spaces, and if left untreated can muddy the sound or make conversation difficult.
At Sontext, we manufacture Serenity Acoustic Panels in a range of thicknesses from 25mm up to 100mm. All thicknesses are independently tested to Australian standards. While thinner panels are ideal for voice-focused spaces like offices or classrooms, thicker ones provide extended performance for low-frequency absorption, ideal for music, theatre, or large multipurpose rooms.
Comparing Panel Thickness and Frequency Absorption
| Panel Thickness | Best For | Low Frequency (125–250Hz) | Mid/High Frequency (500Hz+) |
|---|---|---|---|
| 25mm | Offices, meeting rooms | Low | High |
| 50mm | Studios, classrooms | Medium | High |
| 75mm | Multipurpose halls, theatres | High | High |
| 100mm | Performance & broadcast spaces | Very High | High |
Frequently Asked Questions
Does thicker always mean better performance?
Thicker panels offer greater absorption at low frequencies but may not be necessary in all environments. It’s about matching the panel to the space.
Where would I use a 25mm panel?
In spaces like meeting rooms or hallways where mid-to-high frequency noise (like voices) is the main concern.
When should I choose a 75mm or 100mm panel?
Choose thicker panels when dealing with bass-heavy audio, PA systems, or reverberant environments like sports centres.
Can I mix different thicknesses in one project?
Yes. Many projects use a combination of panel types depending on wall/ceiling locations and acoustic goals.
Are Serenity Panels tested for acoustic performance?
Yes. All Serenity Panels are tested to ISO and Australian acoustic standards and supplied with performance data.

Acoustic Panel Thickness vs Frequency Performance
| Panel Thickness | Low Frequencies (125–250 Hz) | Mid Frequencies (500–1000 Hz) | High Frequencies (2000–4000 Hz) | Best Use Case |
|---|---|---|---|---|
| 25mm | ● Low absorption | ● Good absorption | ● Excellent absorption | Offices, meeting rooms, corridors |
| 50mm | ● Moderate absorption | ● Excellent absorption | ● Excellent absorption | Classrooms, studios, retail spaces |
| 75mm | ● High absorption | ● Excellent absorption | ● Excellent absorption | Theatres, multi-purpose halls, galleries |
| 100mm | ● Very high absorption | ● Excellent absorption | ● Excellent absorption | Music venues, performance spaces, broadcast rooms |
