Very often, a salesperson will accompany you and tell you the number of signs to put to obtain an interesting result. Certainly, this one will give you an overall price for the project. Salespeople often use ratios in terms of floor space that provide correct results. But it seems more relevant to obtain personalized acoustic simulations according to your room characteristics and the panels used. This is what a technician brings. A quote without a technical indicator will be of more limited interest.
Also, an acoustic simulation, even basic, will allow to have a more neutral opinion on the pure acoustic result.
In fact, the raw performance of a acoustic panel can only be assessed in terms of:
- A specific application
- An amount
- A placement
An acoustic simulation can highlight that an ultra-efficient panel on paper will not bring satisfaction once installed if the quantity applied is not sufficient.
It therefore makes sense not to compare project prices that lead to the same result. A project that ends with a reverberation time of 0.6 and one that ends with a reverberation time of 1.2 on the same frequencies does not sound the same at all.
It is therefore wise not to reason in price per panel, but:
- In price per project
- Looking at the gain in terms of reverberation time
- With comparing similar technical services
- With ethical criteria, if it matters to you
