Church Audio Assessment with New Flooring

I'm looking for a professional to evaluate the impact of new carpet flooring on our church's audio quality in the main sanctuary hall. We are considering tile and/or carpet and are wondering if this will affect the sound quality in the service. Currently, we have a combination of tile and carpet that, due to the age of the church, experts have stated may contain asbestos. We will be removing said carpet/tile, testing for asbestos, and then installing new flooring after it is determined that there is no danger of asbestos contamination. We would like a consultation on what direction we should take with the new flooring. The demographic of our congregation is mostly elderly, for which we would like to choose flooring that will not be detrimental to the sound quality of our audio equipment.

Key concerns include:
- Echo and reverberation
- Clarity of speech

Ideal skills and experience:
- Acoustic engineering
- Experience with church audio systems
- Knowledge of flooring impact on sound

Please provide a detailed assessment and recommendations to mitigate any negative effects.
