Join The National Council of Acoustical Consultants


Join an international community of more than 130 firms in 12 countries.

NCAC accepts professional firms that specialize in acoustical consulting based upon education, references, and most importantly – the proven experience of the principals of the firm. NCAC members hold themselves to high standards of professionalism by adhering to a Canon of Ethics and following guidelines for attribution of credit.

To qualify to be an NCAC member, the firm principals who practice acoustical consulting must be a full Member (or Fellow) of either Acoustical Society of America, The Institute of Noise Control Engineering USA, or the Audio Engineering Society. These associations have their own rigorous standards applying to education, demonstrated experience, and references from professional peers. With approval of the Board of Directors in specific circumstances, NCAC Principals may be accepted based on full membership in alternative technical societies or alternative professional credentials or licensing based specifically on knowledge and experience in acoustics.  Membership Criteria and Application Process
