Dear Stockholder:

     You are cordially invited to attend the Annual Meeting of Stockholders of
Sonics & Materials, Inc. (the "Company") which will be held at the Ethan Allen
Inn, Danbury, Connecticut on Tuesday, December 18, 2001, at 10:00 a.m. local

     1.   To elect four directors, each for a term of one year or until their
          respective successors are elected and qualified;

     2.   To ratify the appointment by the Board of Directors of Schneider &
          Associates LLP as independent accountants for the fiscal year 2002;
          and

     3.   To transact such other business as may properly come before the
          meeting or any adjournment or postponement thereof.

     These items are fully discussed in the following pages, which will be made
part of this Notice. Only stockholders of record on the books of the Company at
the close of business on October 16, 2001 will be entitled to vote at the
meeting. The transfer books of the Company will not be closed. A list of

     Stockholders are requested to sign, date and return the enclosed proxy as

retain the right to revoke them at any time prior to the voting thereof by
filing written notice of such revocation with the Secretary of the Company, by
submission of a duly executed proxy bearing a later date or by voting in person
at the Annual Meeting of Stockholders. Attendance at the Annual Meeting will not

                                              By Order of the Board of Directors

                                 PROXY STATEMENT
                              --------------------

                       2001 ANNUAL MEETING OF STOCKHOLDERS

     The enclosed proxy is solicited by the Board of Directors of Sonics &
Materials, Inc. (the "Company") for use in voting at the Annual Meeting of
Stockholders to be held at the Ethan Allen Inn, Danbury, Connecticut on Tuesday,
December 18, 2001, at 10:00 a.m. local time, and at any postponement or
adjournment thereof, for the purposes set forth in the attached notice.

VOTING AND REVOCABILITY OF PROXIES

     The persons named in the enclosed form of proxy will vote the shares for
which they are appointed in accordance with the directions of the stockholders
appointing them. In the absence of such directions, such shares will be voted
FOR proposals 1 and 2 listed below and, in the best judgment of the persons
named in the enclosed proxy, will be voted on any other matters as may come
before the meeting. Any stockholder who executes a proxy has the power to revoke
the same at any time before it is voted by filing written notice of such
revocation with the Secretary of the Company, by submission of a duly executed
proxy bearing a later date or by voting in person at the Annual Meeting of
Stockholders. Attendance at the Annual Meeting will not in and of itself
constitute revocation of a proxy. Any written notice revoking a proxy should be
sent to Secretary, Sonics & Materials, Inc., 53 Church Hill Road, Newtown,
Connecticut 06470. A return envelope which requires no postage if mailed in the
United States is enclosed for your convenience.

     The principal executive offices of the Company are located at 53 Church
Hill Road, Newtown, Connecticut 06470. The approximate date on which this Proxy
Statement and the accompanying form of proxy will first be sent or given to the
Company's stockholders is Friday, October 26, 2001.

RECORD DATE AND SHARE OWNERSHIP

     Only holders of shares ("Shares") of Common Stock, par value $.03 per share
("Common Stock"), of record at the close of business on October 16, 2001 are
entitled to vote at the meeting. On the record date there were outstanding
3,520,100 Shares. Each outstanding Share is entitled to one vote upon all
matters to be acted upon at the meeting. The holders of a majority of the issued
and outstanding Shares, present in person or represented by proxy, shall
constitute a quorum.

     The affirmative vote of a plurality of the votes cast by all stockholders
entitled to vote thereon is required to elect directors (Proposal No. 1).
Therefore, those nominees (up to the number of directors to be elected)
receiving the highest number of votes will be elected. The affirmative vote of a
majority of the votes cast by all stockholders entitled to vote thereon is
required to ratify the appointment by the Board of Directors of the independent
auditors (Proposal No. 2) and generally to act upon any other matter as may
properly come before the meeting or any adjournment thereof. Both abstentions
and proxy holders with authority to vote on at least one matter scheduled to
come before the meeting are counted as "present" for the purposes of determining
whether there is a quorum for the meeting. Abstentions have the effect of a
negative vote on proposals requiring the approval of a majority of the Common
Stock and, due entirely to the method of calculating a plurality, have no effect
on the election of directors. Because broker non-votes are not entitled to a
vote, they are not considered in any way when determining whether any proposal
for which the broker withheld authority was approved.

PROPOSAL 1
ELECTION OF DIRECTORS

     At the meeting, four Directors will be elected by the stockholders to serve
until the next annual meeting or until their successors are elected and
qualified. The accompanying form of proxy will be voted for the election as
Directors of the four persons named below, unless the proxy contains contrary
instructions. Proxies cannot be voted for a greater number of persons than the
number of nominees named in the Proxy Statement. Management has no reason to
believe that any of the nominees will not be a candidate or will be unable to
serve. However, in the event that any of the nominees should become unable or
unwilling to serve as a Director, the proxy will be voted for the election of
such person or persons as shall be designated by the Directors.

                            REPORT OF AUDIT COMMITTEE

     The Audit Committee of the Board of Directors is composed of three members,
two of which are outside directors. It oversees the company's system of internal
controls, financial reporting practices and audits to determine that their
quality, integrity and objectivity are sufficient to protect stockholder
interests. The Audit Committee is assisted in its efforts by Schneider &
Associates LLP, the Company's independent auditors. The Audit Committee reviews
the work done by the independent auditors each year and determines whether to
recommend to the Board of Directors such auditors, or other auditors, to perform
the annual audit for the following year. The Board of Directors is in the
process of adopting a written charter for the audit committee.

     The Audit Committee met once, with management present, during 2001 to
review the overall audit scope, plans and results of the internal audits and
independent audits, the Company's internal controls, emerging accounting issues,
officer and director expenses, audit fees, goodwill and other intangible values.
Based upon its review and discussions, the Audit Committee recommended to the
Board of Directors that the annual financial statements for the year ended June
30, 2001 be included in the Company's Annual Report to Stockholders and in the
Company's Annual Report on Form 10-KSB that was filed with the Securities and
Exchange Commission. The Audit Committee also recommended to the Board that
Schneider & Associates LLP be reappointed for fiscal year ending June 30, 2002,
subject to the ratification of stockholders at the annual meeting.

     The Audit Committee is satisfied that the internal control system is
adequate and that the Company employs appropriate accounting and auditing
procedures.

Members of the Audit Committee:

                                   PROPOSAL 2
               RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

     Schneider & Associates LLP has been designated by the Board of Directors,
subject to ratification by the Company's stockholders, to make an examination of
the consolidated balance sheet of the Company as of June 30, 2002 and the
related consolidated statements of income and cash flows for the fiscal year
ending June 30, 2002, and for such other purposes incidental thereto as may be
required. Schneider & Associates, LLP has been the Company's independent
accountants since April 24, 1998.

     The Company expects that a representative of Schneider & Associates will be
present at the meeting and will be available to respond to appropriate questions
from stockholders. The representative from Schneider & Associates will have an
opportunity to make a statement at the meeting if he or she so desires.

     THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS A VOTE FOR THE
RATIFICATION OF SCHNEIDER & ASSOCIATES LLP AS THE COMPANY'S INDEPENDENT
AUDITORS. PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE SO VOTED UNLESS
STOCKHOLDERS SPECIFY IN THEIR PROXIES A CONTRARY CHOICE.

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's Directors and executive officers and persons who own more than 10%
of the Company's Common Stock or other equity securities to file with the
Securities and Exchange Commission (the "SEC") initial reports of ownership and
reports of changes in ownership of Common Stock and other equity securities of
the Company on Forms 3, 4 and 5. Officers, Directors and 10% shareholders are
required by SEC regulations to furnish the Company with copies of all Forms 3, 4
and 5 they file. Based solely on a review of the copies of such reports
furnished to the Company, the Company believes all Section 16(a) filing
requirements applicable to its officers, Directors and 10% beneficial owners
were complied with during the fiscal year ended June 30, 2001.


                                  OTHER MATTERS

     The management of the Company does not know of any matters other than those
stated in the Proxy Statement which are to be presented for action at the
meeting. If any other matters should properly come before the meeting, it is
intended that proxies in the accompanying form will be voted on any such matters
in accordance with the judgment of the persons voting such proxies.
Discretionary authority to vote on such matters is conferred by such proxies
upon the persons voting them.

     The Company will bear the cost of preparing, assembling and mailing the
proxy, Proxy Statement and other material, which may be sent to its stockholders
in connection with this solicitation. In addition to the solicitation of proxies
by use of the mails, officers and regular employees of the Company may solicit
the return of proxies. The Company may reimburse persons holding stock in their
names or in the names of other nominees for their expenses in sending proxies
and proxy material to principals. Proxies may be solicited by mail, personal
interview, telephone and fax.

     The Company will provide without charge to each person being solicited by
this Proxy Statement, on the written request of any such person, a copy of the
Annual Report of the Company on Form 10-KSB for the year ended June 30, 2001 (as
filed with the Securities and Exchange Commission) including the financial
statements and the schedules thereto. All such requests should be directed to
Lauren H. Soloff, Secretary, Sonics & Materials, Inc., 53 Church Hill Road,
Newtown, Connecticut 06470.


                  STOCKHOLDER PROPOSALS FOR 2002 ANNUAL MEETING

statement to be presented at the next Annual Meeting of Stockholders must be
