"Best Practical facilities in India Which I had seen. Also Very Dedicated Staff’s which really contribute to the learning environment."



"Excellent Training and Practical facilities compared to all other in India, But I feel Decibel can have certain compromise on Duration of certain program because it not getting completed in specified schedules due to excess of activities."

Ratheesh K


"Actually Bridging the Gap is really experienced through the students from Decibel, we hired many from many engineers for different projects but we experienced only 30% will be good in knowledge or practical’s. Some of them might have seen things but don’t have hands on practice to demonstrate it. But when it comes to Students of Decibel we can confidently submit them in front of Client for Test that so far we have attained 70-85% Success rating which is extremely good than many other. I will definitely Hire candidate from decibel for future requirements."

Petter Paul


"The Best Training Centre for QA/QC and Related Studies. Plenty of Practical Equipment’s and Specimens which will give us a real field practical experience and when i entered into the job i was able to clear the client interview and test the very first attempt and this was only possible because i have chosen Decibel as my Training School. If you are serious about learning and obtaining a Job in this industry then you should choose Decibel … If you are coming for Just Time Pass it’s better to not opt Decibel, because their policies and training are inline with the site requirements and hence it may feel little hectic for such candidates."

Ajmal K K


"Excellent Training and Good Practical Facilities with Wide Range of Equipment’s and Lots of Training Samples and Practice Samples. When The Feedback form asked me for 2 things Dislike on Decibel i have suggested the number of specimens we are getting for practicals and it’s complication, but when i reached the Job field i realized that it was a truly great experience which really crafted me to be a perfect in Welding Inspection because all the possible huddles in the industry were covered during the practicals and theoretical training session. Thanking Team Decibel for continuous support and the Placement opportunity given Without Any Doubt I can Recommend Decibel as the Best NDT, Coating, Welding Engineering, QA/QC Training Institute in Kerala and Perhaps in India Itself ( based on the feedback received from my other friends done qc ndt course from other centers across India."
