Election officials drew flak here on Friday when they used the banned cone type loudspeaker for election awareness campaign.

Though the use of cone type speaker has been banned and also the Election Commission had issued a circular against any use of cone speakers during the period in which model code of conduct is in force, the cone speakers were seen fitted on an auto rickshaw that was used as pilot in the rally.

The about-a-kilometre-long rally that started from Corporation office and ended at Collecotrate, was attended by students, NGO members and election officials including Collector G. Govindaraj, all walking closely behind the vehicle fitted with the speakers.

When contacted, the Tamil Nadu Pollution Control Board (TNPCB) sources told The Hindu that the use of cone type speakers was not permitted on any day by anyone as per the Noise Pollution (Regulation and Control) Rules.

“Besides this, there has been a circular from the Chief Electoral Officer (CEO), dated March 6, to the Principal Secretary (Home) to the State Government in which it was stated that only box type speakers should be allowed when the model code of conduct is in force,” Board sources added. The said circular from CEO had been sent to the TNPCB district offices as well as to district administrations across the State.
