super( heterodynes.( After( visiting( an( international( meeting( on(
electronics(and(audio,(he(found(out(that(high(fidelity(sound(was(his(
passion.(After(building(a(lot(of(amplifiers,(loudspeakers(and(record(
players( and( after( finishing( his( secondary( school( he( wanted( to(

(
He( began( his( professional( career( as( a( developer( of( professional( microphones( and(
loudspeakers( at( Philips( Electronics( in( Eindhoven,( The( Netherlands,( in( 1964.( He( received( a(
B.Sc.( degree( in( physics( and( developed( several( types( of( magnetoFdynamic,( piezoelectric,(
electrodynamic( and( electret( transducers( for( commercial,( professional( and( security(
applications.( In( 1977( he( began( working( as( an( applications( engineer( for( professional( audio(
systems.(In(this(capacity(he(educated(and(supported(sales(and(project(engineers(worldwide(
within(the(Philips(Electronics(organization(in(the(design(and(realization(of(emergency(sound(
systems,( e.g.( in( sports( stadiums,( emporiums,( airports,( and( congress( centers.( He( earned(
patents(for(active(absorption(and(reflection(systems(and(capacitive(transducers.(
(
From( 1987,( as( group( manager,( he( gathered( extensive( application( knowledge( about(
worldwide(data(networks,(videoconference(systems(and(digital(audio(communications.(He(
worked( together( with( scientists( for( the( application( of( an( automatic( interpretation( system(

(
Since( the( beginning( of( 1998,( he( has( been( an( independent( consultant( for( acoustics( and(
electro( acoustics.( Together( with( scientists( of( the( research( lab( at( Philips( Electronics( he(
